At a local fitness center, members pay a $12 membership fee and $3 for each aerobics class. nonmembers pay $4 for each aerobics class. for what number of aerobics classes will the cost for members and nonmembers be the same?

For 12 number of aerobics classes, cost for members and nonmembers is same

Solution:

Let "x" be the number of aerobic classes

At a local fitness center, members pay a $12 membership fee and $3 for each aerobics class

Therefore,

Members pay = 12 + 3(number of classes)

Members pay = 12 + 3x eqn 1

Nonmembers pay $4 for each aerobics class

Nonmembers pay = 4x eqn 2

For cost for members and nonmembers be the same, eqn 1 must be equal to eqn 2,

12 + 3x = 4x

4x - 3x = 12

x = 12

Thus for 12 number of aerobics classes, the cost for members and nonmembers will be same
