Question

Find how much you save by buying the bike at store a

Answer 1

Let the price of a bike at Store B be k

The price of a bike at Store A is 5/6 of the price at store B, which means

`=(5)/(6)* k=(5k)/(6)`

If the price of a bike at Store A is $150.60, i.e

`(5k)/(6)=150.60`

Solve to find k, i.e the price of a bike at Store B

Crossmultiply

`\begin{gathered} (5k)/(6)=150.60 \\ 5k=150.60*6=903.6 \\ 5k=903.6 \\ \text{Divide both sides by 5} \\ (5k)/(5)=(903.6)/(5) \\ k=\text{ \$180.72} \end{gathered}`

The price of a bike at store B is k = $180.72

The amount saved if the bike is bought at Store A is

`=180.72-150.60=\text{ \$30.12}`

Hence, the amount saved by buying the bike at Store A is $30.12
