All students from the university get a 5% discount at all stores in the mall, if james spends $86.24 at the video store before his discount, how much will his total bill be after the discount?

.05 *86.24=4.31

86.24-4.31=81.93. The discounted price is $81.93

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
