Question

if 5lb of cheese cost $18.50 how much would 1lb cost

Answer 1

5lb ----> $18.50
1lb ----> $18.5/5
Why?
Because it when you divide price/weight you get the price of 1 unit of the weight!
That means that you'll know how much 1 lb'd cost!
So now if it was how much would 2 lb cost then it'd have been 18.5 * 2/5
Got it? :)

Answer 2

yea thanks
