Answer:
$53.90
Step-by-step explanation:
30% of $77 = $77 * 30/100 = $77 * 0.3 = $23.10 (discount)
Regular price is $77, discount is $23.10, so the item is now
$77 - $23.10 = $53.90
Shorter way of solving this could be as follows:
The regular price is 100% of the price. If the item is on 30% discount, so it means now it worths 70% (which is 100% - 30%) of the regular price:
$77 * 70/100 = $77 * 0.7 = $53.90
