Answer:
The answer is 500
Step-by-step explanation:
STEP 1: Convert interest rate of 2% per 6 months into rate per year.
rate per year = rate per 6 months x 2 = 2% x 2 = 4%
STEP 2: Convert 9 months into years.
9 months = 9/12 years = 0.75 years
STEP 3: Find principal by using the formula <em>I = P x i x t</em>, where<em> </em>I is interest, P is total principal, i is rate of interest per year, and t is total time in years.
In this example I = $15, i = 4% and t = 0.75 years, so
<em>I = P x i x t</em>
<em> P = I/i x t</em>
<em> P = 15/0.04 x 0.75</em>
<em> P = 500</em>
