At a local fitness center, members pay a $20 membership fee and $3 for each aerobics class. nonmembers pay $5 for each aerobics class. for what number of aerobics classes will the cost for members and nonmembers be the same?

For this case, the first thing we should do is define a variable.

We have then:

x: number of classes

We now write the equations that model the problem:

With membership:

members pay a $ 20 membership fee and $ 3 for each aerobics class:

Without membership:

Nonmembers pay $ 5 for each aerobics class:

Then, by equating both equations we have:

Clearing x we have:

The number of aerobics classes that the cost for members and nonmembers will be the same is:

it will be a cylinder. with a diameter of 8 and 4 single pieces high
