To purchase two new copiers, a campus bookstore paid $1350 in interest on a 9% loan for 3 years. Find The principal

$1350/(0.09)(3)=4500.00 for principal

1350 = p * 0.09 * 3

1350 = 0.27p

1350/0.27 = p

5,000 = p

Wow, it seems like those copiers are getting quite the interest! But don't worry, I've crunched the numbers and it seems like the principal amount for the loan is $4500. Now that's a lot of giggles!

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

Simple Interest = Principal × Interest Rate × Time

In this case, we know the simple interest is $1350, the interest rate is 9%, and the time is 3 years. Let's substitute these values into the formula:

$1350 = Principal × 0.09 × 3

Now, let's solve for the principal:

Principal × 0.27 = $1350

Divide both sides of the equation by 0.27:

Principal = $1350 / 0.27

Simplifying the right side:

Principal = $5000

Therefore, the principal amount for the loan is $5000.

To find the principal, we need to rearrange the formula for calculating simple interest:

Simple Interest = Principal x Interest Rate x Time

In this case, we know the simple interest is $1350, the interest rate is 9% (or 0.09 as a decimal), and the time is 3 years. We can plug these values into the formula and solve for the principal:

$1350 = Principal x 0.09 x 3

Divide both sides of the equation by 0.09 x 3 to isolate the principal:

$1350 / (0.09 x 3) = Principal

Simplifying:

$1350 / 0.27 = Principal

The principal is:

$5000

Therefore, the campus bookstore paid $5000 for each copier.
