Answer:
New price = Initial price(1.75) ;
$21
Explanation:
Given that:
Original price = $12
Percentage increase = 75%
The percent equation :
Initial percentage = 100%
Proposed % increase = 75%
New price = initial price(100% + 75%)
New price = Initial price(1 + 0.75)
New price = Initial price(1.75)
The New price is thus ;
$12 * 1.75 = $21
