Question

An 8ft length of 4 inch wide crown molding costs $14. How much will it cost to buy 32 ft of crown molding?

Answer 1

It will cost $56 to buy 32 ft of crown molding.

Explanation

Suppose, the cost of 32 ft of crown molding is  $x$ dollar.

Given that, 8 ft length crown molding costs $14.

According to the ratio of "length" of crown molding to the "cost", the equation will be.......

$\frac{8}{14}= \frac{32}{x}\\ \\ 8x=14*32=448\\ \\ x=\frac{448}{8}=56$

So, it will cost $56 to buy 32 ft of crown molding.
