A rectangular trunk has a volume of 26,880 cubic inches. The trunk is 48 inches long by 28 inches wide. What is the trunk’s height?

Step-by-step explanation:

You can use a ratio and cross multiply to get your answer.

20 pounds       1 pound

 =

      $11                 $ X

Forget about the units of measurement for now and just do the cross multiplying with the numbers  to solve for X.

(20) x (X) = (1) x 11   then divide both sides of the equal sign by 20

20X         11

=    the 20 on top and bottom on the left side cancel out.

20            20

So you are left with X = 11/20  which is  $ 0.55
