Keira Potter · Answer 1

Fitness Center A is cheaper than Fitness Center B!

Kasen Trevino · Answer 2

Center A : 375 per yr

Center B : 35 + 12 (12) + 5 (52) = 35 + 144 + 260 = 439 per yr

I multiplied 12 * 12 because it was $ 12 a month and there are 12 months in a yr. I multiplied 5 * 52 because each aerobic class is $ 5 per class, and she went once per week, and there are 52 weeks in a yr.

so the cheaper one is Center A
