#### Explanation:

It costs $1.40 for $1$pound. You wish to know the cost of $16.2$pounds. That means the price must be raised $16.2$times. ($1.40)/"1 lb" xx "16.2 lb" = $22.68 Remember $1.40 xx 1 pound will give you the same amount, thus the more the amount of pounds increases, so too must the price increase at that rate.
