Question

Jill buys two bracelets for $5 each and a party dress for $150. She also spends $40 on a pair of shoes.

What percentage of the total sale did she spend on shoes?

Answer 1

`2\cdot\$5+\$150+\$40=\$200-total\ spend\\\\\begin{array}{ccc}\$200&-&100\%\\\\\$40&-&p\%\end{array}\ \ \ \ |cross\ multiply\\\\\\200p=40\cdot100\ \ \ \ |divide\ both\ sides\ by\ 200\\\\p=(4000)/(200)\\\\\boxed{p=20\%}\leftarrow answer`
