Question

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. If the bike is then discounted by 20%, how much will Andre pay (before tax)?

Answer 1

4% in addition of the original price

Step-by-step explanation

Let

x represents the original price fo the bike,The bike store marks up the wholesale cost of all of the bikes they sell by 30%

, Andre will pay 130% of the original price

`10\text{ percent=}(130)/(100)=1.3`

the price will be

`\begin{gathered} \text{price}=x\cdot1.3=1.3x \\ \text{price}=1.3x \end{gathered}`

No, if the bike is discounted by 20%, it measn Andre will pay 80 percent of the price

`\begin{gathered} price_(f\in al)=1.3x\cdot(80)/(100) \\ \text{price}=1.04\text{ x} \end{gathered}`

it means Andre will pay and increase of 4 percent (in addition) of the original price,
