Which function models the amount of fertilizer in cubic yards left after w weeks?(1 point)f(w)=64,000(1.98)w f(w)=64,000(1.02)w f(w)=0.98(64000)w f(w)=64,000(0.98)w

Answer 1

f(w) = 64,000(0.98)^w

Explanation: a 2% weekly decrease means multiply by 1 − 0.02 = 0.98 each week, with initial amount 64,000.
