Since harper has only %15 that is the most she can spend, therefore we would have 15> or = 4.75b+3.5c. the best way to solve this would be to divide 15 by 4.75, then round down to the nearest whole number. if you do this, you get 3 bags of fruit.
15 + 7 + 9 + 7 + 4 + 4 + 3 + 3 = 52
First do 48.50-21 then divide that amount by 5. Then that’s how much each pair of socks cost so
48.50-21=27.50
27.50%5=$5.50 so rx=$5.50
