Answer:
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
