Step-by-step explanation:
, 
of the usual price is the savings .
<u>Step-by-step explanation:</u>
Here we have , At a hardware store, a tool set normally costs $80. During a sale this week, the tool set costs $12 less than usual. We need to find What percentage of the usual price is the savings . Let's find out:
Initially we have cost as $80 , in sale it is $12 less i.e.
⇒ 
⇒ 
So , percentage of the usual price is the savings :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒
Therefore , of the usual price is the savings .
