Answer:
$404.13
Explanation:
First, you start by adding together 599, 49, and 61, which gives you 709. Then, you want to do 709(1.19) to find the amount he would pay including interest in a year, and your answer is 843.71. You want to next subtract that by 709, so you do 843.71-709, and get 134.71. Finally, since it says 3 years, you have to multiply that by 3, and 134.71(3) gives you your final answer, $404.13. I hope this helped you understand better!
