The Math Club plans to pay a visitor $280 to speak at a fundraiser. Tickets will be sold for $7 each. Find an equation that gives the profit/loss for the event as it varies with the number of tickets sold.  How many people must attend the event for the club to break even?

Answers

A minimum of 40 people must attend the event for the club to breakeven such that the cost of the speaker to speak is \$280 and the selling price of a ticket is \$7.

Breakeven

Breakeven is a point where the cost price and the selling price of the commodity are the same. In other words, the seller is neither is loss nor in profit.

We will first determine the breakeven point and equate it with the total amount received by selling the tickets to determine the minimum number of tickets to be sold to attain the breakeven.

How to determine the breakeven point?

Let the number of tickets sold be x.

According to the question,

The fundraiser will be in profit if, 7x > 280

The fundraiser will be in loss if, 7x < 280

Now, to determine the breakeven point-

7x=280\nx=(280)/(7)\nx=40

Thus, a minimum of 40 people must attend the event for the club to breakeven.

#SPJ2

Equation:
Profit = Price of tickets*number of tickets - initial cost

Let t be the number of tickets
Let p be the profit
p = 7t-280


To Break Even:
In order for the club to break even, p must be equal to 0, and so the equation can be rewritten as:
0 = 7t-280
7t = 280
t = 280/7
t = 40 tickets

What do we use geometry for in real life??????????

Answers


Reading the other answer that somebody submitted, we realize that
geometry has no uses at all in real life.

Except if you're building a road, a bridge, a house, a concrete pad for a
barbecue grill, a support for your tomato plants, a TV antenna, or a border
for a garden.  There are no other uses for it.

Except if you're trying to figure out how far that point on the other side
of the highway is from you, or how high your house is.  Otherwise there
is no use for geometry.

Except if you need to know how many bicycle wheels you can fit into
the carton you have, or how much yellow string you need to make a
string fence around your circular garden, or how much carpet you need
to buy in order to put new carpet in your bedroom, or how much paint
you need to buy in order to paint the garage.  Other than those rare
occasions, you'll never use geometry in real life.

Unless you go to school.  School is a small part of your real life where they
try to pound enough into your head so that you won't be a total flop in the
rest of it.  It isn't easy.  One of the ways they try to do that is to give you
gym, where you build the arm and leg muscles that you'll need if you ever
try to walk around or work at a job outside of school.  Another way they try 
to do it is to give you things to think about, like English and Geometry,
where you build the brain muscles that you'll need if you ever need to
think your way out of a paper bag during the rest of your real life.

Say hi to your uncle Holden for me.

Which of the following is another way to express the equation 16 = -9 + z?

Answers

Since you didn't give the options, we'll answer In steps and you can pick which step you have as an answer choice...

16 = -9 + z

Add 9 to each side for

16 + 9 = z (that's one option)

Add like terms for

25 = z (there's another)

You could also go a whole different route and take the original equation

16 = -9 + z

subtract z from each side for

16 - z = -9

Any of those would be another way to express the equation.

Answer:

16 = -z - 9

Step-by-step explanation:

umm yeh hope this helps?

Use the elimination method1) 3x+y=-1 5x-y=9
2) 4x+6y=24 4x-y=10
3)2x-y=-3 x+3y=16
4) 2x+3y=7 3x+4y=10

Answers

1) 3x+y=-1 5x-y=9
    First of all we have add both equation but to be sure that the value we want to eliminate are both in a way that would make it possible t be deleted.
    3x+y=-1 
    5x-y= 9
    8x = 8
      x= 1
In this case we are able to eliminate y becuase if we add +y-y we get that our answer is 0. and 3x + 5x would be 8x and -1+9 would be equal to 8 and to find x we needed to divided giving us that the answer for x is 1 becuase 8/8 is 1.
Then to find y we substitude the value of x in any of the formulas.
3(1)+y= -1
 3+y= -1
 y= -1-3
 y=-4
When we have our y value we can determine if it is correct by replace the values.
5(1)--4= 9
5+4= 9
9=9
Up until now we are fine. So we do the same with the other equation.
3(1)+-4=-1
3+-4=-1
-1=-1 
So by this we can now detemine that.
x= 1
y= -4

2) 4x+6y=24 4x-y=10 
4x+ 6y =24
    4x-y=10 (*-1)
    4x+6y=24
    -4x+y=-10
    7y= 14
     y= 14/7
     y= 2
In this case we are not able to delete any of the variables so we multiplied by -1 to be able to eliminate x. 
Then to find x we substitute the value of y in any of the formulas.

     
4x-2=10 
     4x= 10+2
     x= 12/4
      x= 3
So we now know our variables so we substituted them to see if they are correct.
      4(3)+6(2)=24 
      12+12=24
       24=24
We do the same with the other equation.
      4(3)-2=10
      12-2 =10
       10= 10
So we can assume that.       
       x= 3
       y= 2

3)2x-y=-3 x+3y=16
  (3*)2x- y= -3 
    x+ 3y = 16
   6x -3y = -9
    x+3y =16
   7x= 7
   x= 1
In this case we are not able to delete any of the variables so we multiplied by 3 to be able to eliminate y. 
Then to find y we substitute the value of x in any of the formulas.

    1+ 3y = 16
 3y= 16-1
 y= 15/3
 y= 5 
So we now know our variables so we substituted them to see if they are correct.
2(1)- 5 =-3
2-5= -3
-3= -3
We do the same with the other equation.
1+3(5)= 16
1+15=16
16=16
So we now are sure that
x= 1
y= 5

4) 2x+3y=7 3x+4y=10
2x+3y =7 ( * - 4)
3x+4y =10 ( * 3)
-8x -12y = -28
9x +12y = 30
x= 2
In this case we are not able to delete any of the variables so we multiplied one of teh quations by - 4 to be able to subtract in our sum and the other by 3 to have the same number on y to be able to eliminate y. 
Then to find y we substitute the value of x in any of the formulas.

2(2)+3y= 7
4+3y=7
3y= 7-4
y= 3/3
y= 1
So we now know our variables so we substituted them to see if they are correct.
3(2)+4(1)= 10
6+4=10
10=10
We do the same for the other
2(2)+3(1)=7
4+3= 7
7=7
So with that we can say that.
x= 2
y= 1
