Question

Eva makes a few dozen cupcakes and sells them for $8 a dozen. Which function represents the relationship between the money Eva earns, m, and the number of cupcakes she sells, c? A. f(c) = c × 8. B. f(m) = c × 8. C. f(c) = m × 8. D. f(m) = m × 8. E. f(m) = c × m

Answer 1

A. f(c) = c × 8

Answer 2

we let c represent the number of dozen cupcakes in which the problem says that the cost of each cupcake is $8 per dozen. In this case, the money earned by Eva should be a function of the number of dozen cupcakes. In this case, the expression that represents this is  A. f(c) = c × 8
