John brought 20 water melons each water melon cost him 2 dollars. He gave his friend Bob 3/4 of the watermelons. In return bob gave him double the amount of water melons back. How many watermelons does John have now? How much money did he spend on each water melon?
I believe your answer is C, because Y (payment after taxes) is x (what he recieved the first time) minus taxes (0.18%) Hope this helped!
21 = 4.8
8 x 2.1 = 16.8 - 12 = 4.8
