Charlie bought a 2and 1 half bag of oranges for $3.75.What is the cost of one pound of oranges?

Answers

Charlie buys 2.5 pounds of oranges for 3.75.

To find out how much he will pay for 1 pound of oranges, use the proportion

2.5/3.75 = 1/x
Cross multiply to get x = $1.50 per pound of oranges.

Let number be "x"( the cost of one pound of oranges ) ;
( 2 1 / 2 )x = 3.75 ;
( 5 / 2 )x = 375 / 100 ;
x = ( 375 / 100 )×( 2 / 5 ) ;
x = 750 / 100 ;
x = $7.50 ;

16. A clerk is marking up merchandise 28%The original price of an item is $499.
What will be the retail price?

Answers

Step-by-step explanation:

Original Price = $499

100% of something is the original price. when you mark something up, you are increasing the price. when the clerk marks up merchandise by 28%, they are increasing the price by 28%.

This means that the price is original + markup = 100 + 28 = 128%

Therefore, the retail price is

499 x 128% = $638.72

2. Members of the band sold soda and popcorn at a college football game to raisemoney for an upcoming trip. The band raised $2,000. The amount raised is divided

equally among the m members of the band.

Which equation represents the amount, A, each member receives?

A. A=

m

2.000

2.000

B.A

=

C. A = 2,000m

D. A = 2.000 - m

Answers

Answer: $A=(2000)/(m)$

Step-by-step explanation:

Given : Members of the band sold soda and popcorn at a college football game to raise money for an upcoming trip. The band raised $2,000.

The amount raised is divided equally among the m members of the band.

Using division operator , the amount each member gets=2000 ÷ m

or we can write it as $(2000)/(m)$

Now, the equation represents the amount, A, each member receives is given by :-

$A=(2000)/(m)$

Two fifths of the fish in grays fish tank are guppies. One fourth of the guppies are red. What fraction of the fish in grays tank are red guppies?

Answers

it would be one fourth cause he tells you the fraction of how many guppies are red

I think it goes like this:
1/4 of 2/5= 2/20 or 1/10

It's asking what fraction are red guppies and it's telling us that 2/5 of the tank is made up of guppies and out of that 2/5, 1/4 of them are red. So you would have to figure out what 1/4 of 2/5 is to find out how many red guppies there are.

Which of these points lies on the line described by the equation below?y - 4 = -2(x - 6)

A. (-6, -4) B. (-4,-6) C. (6,4) D. (4,6)

Answers

Answer:

Option C is correct.i.e., ( 6 , 4 ) lie on given line.

Step-by-step explanation:

Given Equation, y - 4 = -2 ( x - 6 )

Option A:

From given point, x = -6 and y = -4

LHS = y - 4 = -4 - 4 = -8

RHS = -2 ( x - 6 ) = -2 ( -6 - 6 ) = -2 × ( -12 ) = 24

LHS ≠ RHS

⇒ This point does not lie on given line.

Option B:

From given point, x = -4 and y = -6

LHS = y - 4 = -6 - 4 = -10

RHS = -2 ( x - 6 ) = -2 ( -4 - 6 ) = -2 × ( -10 ) = 20

LHS ≠ RHS

⇒ This point does not lie on given line.

Option C:

From given point, x = 6 and y = 4

LHS = y - 4 = 4 - 4 = 0

RHS = -2 ( x - 6 ) = -2 ( 6 - 6 ) = -2 × ( 0 ) = 0

LHS = RHS

⇒ This point lie on given line.

Option D:

From given point, x = 4 and y = 6

LHS = y - 4 = 6 - 4 = 2

RHS = -2 ( x - 6 ) = -2 ( 4 - 6 ) = -2 × ( -2 ) = 4

LHS ≠ RHS

⇒ This point does not lie on given line.

Therefore, Option C is correct.i.e., ( 6 , 4 ) lie on given line.
