Jennifer belongs to a gym that requires a monthly membership fee of $60 plus an additional $15 fee for each yoga class she attends. Which of the following slope-intercept form equations models the total amount that Jennifer pays monthly? A. y = –60x + 15 B. y = –15x + 60 C. y = 15x + 60 D. y = 60x + 15
Your answer is c. If you use the formula y=mx+b 60 will be your b due to the fact that it doesn't change, but because Jeniffer may need to pay 15 more than once. You will use 15 as your m. Since m is multiplied by x, x being the number of times she has gone to her class, Jeniffer can see how much she must pay monthly
