The cost of the sweater is $33.95.
The markup is 70%.
We are asked to find the selling price
The selling price can be found using
[tex]SP=CP\times\frac{(100\%+MP)}{100}[/tex]Where CP is the cost price, MP is the markup percentage, and SP is the selling price.
Let us substitute the given values
[tex]\begin{gathered} SP=33.95\times\frac{(100+70)}{100} \\ SP=33.95\times\frac{170}{100} \\ SP=\$57.715 \end{gathered}[/tex]Therefore, the selling price of the sweater is $57.715
