Question

Anna wants to take fitness classes. She compares two gyms to determine which would be the best deal for her. Fit Fast charges a set fee per class. Stepping Up charges a monthly fee, plus an additional fee per class. What is the system of equations representing these costs?

Answer 1

$\huge{\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}$

Just do what you said (subsitute) and solve

bsitute) and solvex=number of classes

7.5x=5.5x+10

subtract 5.5x from both sides

2x=10

x=5

5 classes

to find how much it costs, subsitute 5 for x in any equation

y=7.5(5)

y=37.5

total cost is $37.5 per month.

Hope!it's help u ....XD
