Question

Solve I=PRT for P if I=312.50, r=25%, and T=0.25

Answer 1

Answer: I = $ 19.53

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 25%/100 = 0.25 per year,

then, solving our equation

I = 312.5 × 0.25 × 0.25 = 19.53125

I = $ 19.53

The simple interest accumulated

on a principal of $ 312.50

at a rate of 25% per year

for 0.25 years is $ 19.53.

Answer 2

Answer:

P = 5000

You need to multiply r and T together, then divide 312.50 by that.
