Question

At a local fitness center, members pay a $14 membership fee and $3 for each aerobics class. Nonmenbers pay $5 for each aerobics class. For what humber or aerobics classes will the cost for members and nonmenbers be the same?

Answer 1

Fee for members: y = 14+ 3x
fee for nonmembers: y= 5x

to find the number of aerobics classes that will cost the same for 2, you set 2 equation equal to each other:
$14 + 3x = 5x \\ 14 = 2x \\ x = 7$
