**CJ**, Thursday, February 24, 2011 at 4:22amthe first thing you do is divide 30000 with 100:

300 = 1%

multiply it by seven to count the percentage

300x7 = 2100

multiply it by 4 to count the total via years

2100x4 = $8400

The answer is $8400 in total :)

(Interest, I = Principal, P * Rate, R * Time, T

P = 30,000

R = 7% = 0.07

T = 4

I = 30,000 * 0.07 * 4

I = 2100 * 4

I = 8400
