Rate is 9%. Time is 4 years. Simple interest is $354.60. What's the principal? Please show me how you got to the answer as well.

I = PRT

354.6 = P * 0.9 * 4

Solve for P

985

To find the principal, we can use the formula for simple interest:

Simple Interest = (Principal × Rate × Time) / 100

We can rearrange this formula to solve for the principal:

Principal = (Simple Interest × 100) / (Rate × Time)

Given:
Rate = 9%
Time = 4 years
Simple Interest = $354.60

Substituting these values into the formula, we get:

Principal = ($354.60 × 100) / (9% × 4 years)

First, let's convert the rate from a percentage to a decimal by dividing it by 100:

9% ÷ 100 = 0.09

Now, let's substitute the values and solve for the principal:

Principal = ($354.60 × 100) / (0.09 × 4 years)

Principal = ($354.60 × 100) / (0.36 years)

Principal = $35460 / 0.36

Principal = $98,500

Therefore, the principal is $98,500.
