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

$y=\frac{5}{6}x$ ------> equation A

$y=\ 150.60$

Substitute the value of y in equation A

$150.60=\frac{5}{6}x$

Solve for x

Multiply by $\frac{6}{5}$ both sides

$x=\frac{6}{5}*150.60\\\\x=\ 180.72$

Find the difference of the price Store B and Store A

$\ 180.72-\ 150.60=\ 30.12$

therefore

the answer is

$\ 30.12$
