Question

2. 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. What function models the amount of fertilizer in cubic yards left after w weeks?

Answer 1

Answer: f(w) = 78,000 (0.97)^w

Step by step explanation:

The amount of fertilizer in the landscaping company's warehouse decreases by 3% per week

So,

3% ------> .03

now we subtract .03 from 1 and we get .97

1 - .03 = .97

and the function would look like this:

f(w) = 78,000 (0.97)^w
