Answer: $42.48
Step-by-step explanation:
Assuming that the interest is paid monthly, Mr, Gardener will pay the interest only once. First, we must find out exactly how much, in dollars, the interest is.
To do this, we must multiply the total ($36) by the decimal form of the percentage (divide the percentage number by 100 to do so)
18/100= 0.18 = decimal form
36 * 0.18 = $6.48 = amount of interest alone
Thus,
6.48 + 36.00 = $42.48 = Total amount that Mr. Gardener will pay
