At a ski resort, the cost of renting ski equipment for x days can be represented by the function
f(x) = 44x + 8.

the cost of renting ski equipment for x days at another ski resort can be represented by the function g(x) = 30x + 15.

which of the following represents h(x) = f(x) – g(x), the difference in the rental amounts between the resorts?

a) h(x) = 74x – 23
b) h(x) = 74x + 7
c) h(x) = 14x – 7
d) h(x) = 14x + 7
