At a local fitness center, members pay an $8 membership fee and $4 for each aerobics class. nonmembers pay $6 for each aerobics class. for what number of aerobics classes will the cost for members and nonmembers be the same?

Let X be the number of classes:

You need to multiply the cost per class by the number of classes.

For members you also need to add in the membership fee.

Members pay a total of 8 +4x

Non members pay a total of 6x

Set them to equal to solve for x, which is the number of classes taken:

8 + 4x = 6x

Subtract 4x from both sides:

8 = 2x

Divide both sides by 2:

x = 8/2 = 4

The answer is 4 classes.

ad = ae + ed = y + 7

similar triangles therefor

ac/ab = ad/ae

6/4 = (y + 7) / y

cross multiply

6y = 4(y + 7)

6y = 4y + 28

2y = 28

y = 14

step-by-step explanation:

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
