The amount of fertilizer in a landscaping company's warehouse decreases at a rate of 2% per week. The amount of fertilizer in the ware house was originally, 64,000 cubic yards. Which function models the amount of fertilizer in cubic yards left after w weeks?
f(w) = 0.98(64000)^w
f(w) = 64,000(0.98)^w
f(w) = 64,000(1.02)^w
f(w) = 64,000(1.98)^w
The correct function is:
f(w) = 64,000(0.98)^w
