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
I wanna say its b)1 but im not 100% sure. if its wrong im sorry
