The equation should be 80,000(3/4)^t = 33,750
We can find the amount of months needed by replacing the t with a different number, and whichever numbers makes the equation true, is the correct response.
After doing this, we know that 3 months is the correct response.
So, 80,000(3/4)^t = 33,750, and 3 months are the correct responses.
