Mr. Gardner had to borrow $36.00 to buy a new backpack for his daughter. The store charged him 18% interest. He took 1 month to pay off the loan.

$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
