Question

The price of a bike at Store A is 5/6 the price x (in dollars) at Store B. The price at Store A is $150.60. Write and solve an equation to find how much you save by buying the bike at Store A.

Answer 1

let the price in storeB=x
5/6x=150.6
x=180.72
180.72-150.6=$30.12
you save $30.12

Answer 2

Let

x------> the price of a bike in Store B

y------> the price of a bike in Store A

we know that

`y=(5)/(6)x` ------> equation A

`y=\$150.60`

Substitute the value of y in equation A

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

Solve for x

Multiply by
`(6)/(5)` both sides

`x=(6)/(5)*150.60\\\\x=\$180.72`

Find the difference of the price Store B and Store A

`\$180.72-\$150.60=\$30.12`

therefore

the answer is

`\$30.12`
