What is this math problem?

The formula for *simple* interest is:
I = Prt
P : Principal (1750)
r : annual interest rate as a decimal (0.02)
t : time in years (9)
Just plug those values in:I = 1750 * 0.02 * 9
I = 315
It's more common to find *compound* interest in real life, but this is Math World where it's easier to start with simple interest.

P = P₀ (1+ 0.02)^9
