Question

The scale factor of the dimensions of two similar wood floors is 4:3. It costs $207 to refinish the smaller wood floor. At that rate, how much would it cost to refinish the larger wood floor? $​

Answer 1

$276

Explanation:

Create a proportion where x is the cost to refinish the larger wood floor:

`(4)/(3)` =
`(x)/(207)`

Cross multiply and solve for x:

3x = 828

x = 276

So, to refinish the larger wood floor, it would cost $276
