Question

At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. What percentage of the usual price is the saving? Explain or show your reasoning.

Answer 1

Original cost is $80.
Original cost is denoted by 100%

$80 represent 100%
$1 represent 100 ÷ 80 = 1.25%

Saving is $12
$12 represent 1.25 x 12 = 15%


So $12 represent 15%
