Question

The game cost 85dollars but it's 20% off today how much does the game cost

Answer 1

100% of the cost is $85. To find how much 20% represent, we can use the next proportion:

`\frac{100\text{ \%}}{20\text{ \%}}=\frac{85\text{ \$}}{x\text{ \$}}`

Solving for x,

`\begin{gathered} 100\cdot x=85\cdot20 \\ x=(1700)/(100) \\ x=17\text{ \$} \end{gathered}`

Then, a discount of $17 must be applied. The cost after applying the discount is $85 - $17 = $68
