, [tex]15\%[/tex] of the usual price is the savings .
Step-by-step explanation:
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.
⇒ [tex]80-12[/tex]
⇒ [tex]68[/tex]
So , percentage of the usual price is the savings :
⇒ [tex]\frac{80-68}{80}(100)[/tex]
⇒ [tex]\frac{12}{80}(100)[/tex]
⇒ [tex]\frac{3(4)}{20(4)}(100)[/tex]
⇒ [tex]\frac{3}{20}(100)[/tex]
⇒ [tex]3(5)[/tex]
⇒ [tex]15\%[/tex]
Therefore , [tex]15\%[/tex] of the usual price is the savings .
