Residents of the town of Maple Grove who are connected to the municipal water supply are billed a fixed amount yearly plus a charge for each cubic foot of water used. A household using 1000 cubic feet was
billed $56, while one using 1600 cubic feet was billed $84.
(a) What is the charge in dollars per cubic foot? Give an exact answer.

The amount of fertilizer in a landscaping company's warehouse decreases at a rate of 3% per week. The amount
of fertilizer in the warehouse was originally 78,000 cubic yards.
Which function models the amount of fertilizer in cubic yards left after w weeks?
A
f(w) = 0.97(78,000)"
f(w) = 1.03(78,000)"
f(w) = 78,000(0.97)"
f(w) = 78,000(1.03)W
