The equation I = prt, represents how to solve for interest, I = interest, p = principle, t = time
I = 4,900(0.18)(11) when multiplied all together you get:
I = 9,702; the interest is $9,702
Finding the total: principle + interests; 4,900 + 9,702 = 14,602
-Final Answers-
Interest: $9,702
Total: $14,602
