Sever21 [200]

Answer:

$900

Step-by-step explanation:

Use the formula for simple interest:  i = p r t, where i is the interest earned, p is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years.

Here, i = $27 = p(0.015)(2), or

               $27 = 0.03p

Dividing both sides by 0.03, we get:

p = $27 / 0.03 = $900

The principal, in this situation, was $900.
