You are choosing between two health clubs. Club A offers membership for a fee of $ 14 $14 plus a monthly fee of $ 15. $15. Club B offers membership for a fee of $ 18 $18 plus a monthly fee of $ 14. $14. After how many months will the total cost of each health club be the same? What will be the total cost for each club?

Answers

Answer:

After 4 months total cost of each health club would be the same that is $74.

Step-by-step explanation:

Let x represent number of months.

We have been given that Club A offers membership for a fee of $14 plus a monthly fee of $15.

The total cost of using Club A for x months would be $15x+14$ .

We have been given that Club B offers membership for a fee of $18 plus a monthly fee of $14.

The total cost of using Club B for x months would be $14x+18$ .

Let us equate both equations to find number of months, when both health clubs cost would be same.

$15x+14=14x+18$

$15x-14x+14=14x-14x+18$

$x+14=18$

$x+14-14=18-14$

$x=4$

Therefore, after 4 months the total cost of each health club would be the same.

The total cost of using Club A: $15(4)+14=60+14=74$

The total cost of using Club B: $14(4)+18=56+18=74$

Therefore, the total cost for each club would be $74.

The pair of points (6,y) and (10,-1) lie on a line with a slope 1(over)4. What is the value of y?

Answers

The formula for Slope is m = $(y_2 - y_1)/(x_2 - x_1)$ where m is the slope and the x's and y's are your given coordinates. So, plug the given information into the formula and solve for y.

m = $(y_2 - y_1)/(x_2 - x_1)$ Plug in the given values
$(1)/(4)$ = $(-1 - y)/(10 - 6)$ Cross multiply
10 - 6 = -4 - 4y Subtract
4 = -4 - 4y Add 4 to both sides
8 = -4y Divide both sides by -4
-2 = y Swich the sides to make it easier to read
y = -2

Check your answer by plugging -2 back into the equation with the other values.

[tex] \frac{1}{4} [/tex] = $(-1 - (-2))/(10 - 6)$ Simplify the double negative
$(1)/(4)$ = $(-1 + 2)/(10 - 6)$ Simplify the numerator and denominator
$(1)/(4)$ = $(1)/(4)$

Since both sides equal each other, y = -2.

Use the formula to find the slope which is m= y2-y1 over x2-x2. The equation would look like 1/4= -1 -y over 10-6. First, you do the subtraction in the denominator and you get 4. The equation would look like 1/4=-1-y over 4.

Then, you multiply the 4 to both side in order to get rid of the fraction from the equation. You would then have 1=-1-y. You add -1 to both side and you would have 2=-y. Since the variable cannot be negative, you divide -1 from both side and get -2=y. Therefore the answer is y=-2.

Hope this helps.

51% of the tickets sold at a school carnival were early-admission tickets. If the school sold 100 tickets in all, how many early-admission tickets did it sell?

Answers

Answer:

51 were the total number of the tickets sold at a school carnival wereearly-admission tickets.

Step-by-step explanation:

Total number of tickets sold by = 100

Let $x$ be the early-admission tickets sold by the school.

As 51% of the tickets sold at a school carnival were early-admission tickets.

$x=(51)/(100)* 100$

$= 51$

Therefore, 51 were the total number of the tickets sold at a school carnival wereearly-admission tickets.
