Answer:
$24.60
Step-by-step explanation:
Let x be the original price of the puzzle. We are told the cost is $15.99 AFTER a 35% discount. This can be written as an equation:
(1 - 0.35)*x = $15.99 [The (1-0.35) is the original cost 100% (1) minus the 35% discount (0.35)]
0.65x = $15.99
x = $24.60
CHECK:
Will a 35% discount on an item priced at $24.60 result in a final price of $15.99?
(0.35)*($24.60) = $8.61 discount
$24.60 - $8.61 = $15.99 YES
