Looking at the given question, we can find several important information's and based on thm we can easily calculate the amount after 10 years. Principal amount = $550 Rate of interest per year = 3% Number of years the amount is to be kept = 10 years Now we get put these information's in the formula of finding amount of money kepy in simple interest. Amount = P(1 + rt) Where p = principal amount r = rate of interest t = Time Then Amount = 550[1 + (3/100) * 10)] = 550 [1 + 3/10] = 550 * (13/10) = 55 * 13 = 715 dollars So the total amount in my account will be $715
