Answer:
$28.80
Step-by-step explanation:
Find 20% of original price (original price = $48)
- $48 = 100% --- divide both sides by 5 to reach 20%
- 100% / 5 = 20% and $48 / 5 = $9.60
- 20% = $9.60 (this is the price that Juan thinks is the price he should pay)
Find the price that the store is charging
- $48 - $9.60 = $38.4
- Store price (including the 20% discount)= $38.4
Find the difference in prices between Juan and the storre
- subtract Juan from store price
- $38.4 - $9.60 = $28.8
