Question

Two sisters decide to take a series of acting lessons. One decides to pay a flat rate of $75, shown as f(x). The other just wants to pay $5 per lesson, shown as g(x). Which function shows the correct combination of these two functions to represent the amount the parent should pay, shown as h(x)?

f(x) = 75, g(x) = 5x, h(x) = 5x + 75
f(x) = 75x, g(x) = 5, h(x) = 75x + 5
f(x) = 75, g(x) = 5, h(x) = 5 + 75
f(x) = 75x, g(x) = 5x, h(x) = 75x + 5x
