Question

Find the selling price of a $65 item after a 40% markup.

Answer 1

the selling price is $ 91

Step-by-step explanation

to solve this we can use a rule of three

let x represents the selling price

hence

if

`\begin{gathered} 100\text{ \%}\Rightarrow\text{ \$ 65} \\ \text{then} \\ 140\text{ \%}\Rightarrow\text{ x} \end{gathered}`

hence

the proportion is

`(100)/(65)=(140)/(x)`

solve for x

`\begin{gathered} (100)/(65)=(140)/(x) \\ 100x=140\cdot65 \\ x=(140\cdot65)/(100) \\ x=91 \end{gathered}`

therefore, the selling price is $ 91
