$ 1,100
Explanation:
Well use the simple interest equation;
A = P(1 + rt)
Where:
A = Total Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
r = Rate of Interest per year in decimal; r = R/100
R = Rate of Interest per year as a percent; R = r * 100
t = Time Period involved in months or years
A = 500 (1 + 0.15*8)
A = 500 (2.2)
= 1100
