Question

Due to the effects of COVID-19 pandemic in our country, a certain restaurant’s annual profit went down from $980,000 in 2018 to $840,000 in 2020. If the profit continues a pattern of exponential decay, what will be its revenue on year 2022?

I would appreciate Solutions, thanks!

Answer 1

Look up the formula for exponential decay.

840000 = 980000e^2k

0.85714 ≈ e^2k

ln 0.85714 ≈ 2k

-0.15415 ≈ k

A = 840000e^2(-0.15415)

Can you calculate and answer?
