○=> Correct answer :
The retail price of the skateboard = [tex] \color{hotpink}\boxed{\bold{\tt\bold{\$110}}}[/tex]
○=> Steps to derive correct answer :
Given :
▪︎Cost price of a skateboard in a sports shop = $80
▪︎Percentage of markup in the price of the skateboard = 37.5%
Which means :
The retail price of the skateboard :
= Intial price of skateboard + 37.5% of it's initial price
[tex] = \tt80 + 37.5\% \: of \: 80[/tex]
[tex] =\tt 80 + \frac{37.5}{100} \times 80[/tex]
[tex] =\tt 80 + \frac{37.5 \times 80}{100} [/tex]
[tex] = \tt80 + \frac{3000}{100} [/tex]
[tex] =\tt 80 + 30[/tex]
[tex]\color{plum} = \tt\bold{\$110}[/tex]
Therefore, the retail price of the skateboard = $110
