Answer: $12.60
Explanation:
after adding to the total with the markers, lunchbox and shirts you get $15.75 then multiply the normal price $15.75 by 20 then divide it by one hundred and you will get $3.15 as your saved amount and you will then do 15.75-3.15= 12.6 make sure to put a 0 after the 6 making it 60.
(2.50+5.25+7.99= $15.75)
(15.75-3.15= 12.60)
