Answer:
45
Step-by-step explanation:
HOW TO WORK OUT
cross multiply so $24 is 80% because it was 20% discounted so..
24 = 80%
? = 100%
24 x 100 = 2400
2400 divided by 80 = 30
$30 was the original price
HOW TO CHECK
20% of $30
again you cross multiply so..
$30 = 100%
? = 20%
30 x 20 = 600
600 divided by 100 = 6
$30 - $6 = $24 which was the discounted pricw
