Question

Three ounces of cinnamon cost $2.40. If there are 16 ounces in 1 pound, how much does a cinnamon cost per pound?

Answer 1

Divide the cost for 3 ounces by 3, to find the cost per ounce:

2.40 / 3 = 0.80

It cost 80 cents per ounce.

Now multiply the cost per ounce by 16 ounces:

16 x 0.80 = 12.80

It will cost $12.80 for one pound.
