One day, he bought 10 pairs of socks for $2.50 each
Following is the equation for this info:
⇒ [tex]Money = 10(2.50)[/tex]
⇒ [tex]Money = 25\[/tex]
3 pairs of shoes for d dollars each
Following is the equation for this info:
⇒ [tex]Money = 3(d)[/tex]
⇒ [tex]Money = 3d\[/tex]
He spent a total of $135.97
Following is the equation for this info:
⇒ [tex]Total-Money = 135.97[/tex]
⇒ [tex]25+3d=135.97[/tex]
⇒ [tex]3d=135.97-25[/tex]
⇒ [tex]d=37\[/tex]
Therefore , [tex]d=37\[/tex] .
