Answer:
a) What is the amount off the original price?
= $8.4
b) What is the new price for the pair of shoes?
= $33.6
Step-by-step explanation:
a) What is the amount off the original price?
We are told that:
The sale price is 20% off the original price.
Original price = $42
Hence:
$42 × 20%
$42 × 20/100
= $8.4
b) What is the new price for the pair of shoes?
The new price =
0riginal price - Amount off the original price
= $42 - $8.4
= $33.6
The original price = $33.6
