Answer:
The number of aerobics classes for which the cost for members and nonmembers be same is 7 classes .
Step-by-step explanation:
Given as :
The cost for membership fee = $ 14
The cost for aerobics class for members = $ 4
The cost for aerobics class for nonmembers = $ 6
Let The number of aerobics classes for which the cost for members and nonmembers be same = n classes
So, According to question
The cost for membership fee + ( The cost for aerobics class for members × The number of aerobics classes ) = The cost for aerobics class for nonmembers
I.e $ 14 + ( $ 4 × n ) = $ 6 × n
Or, 14 = 6 × n - 4 × n
or, 14 = 2 × n
∴ n =
I.e n = 7
So, The number of aerobics classes for which the cost for members and nonmembers be same = n = 7 classes
Hence , The number of aerobics classes for which the cost for members and nonmembers be same is 7 classes . Answer
