Question

3 ounces of cinnamon cost $2.40. if there are 16 ounces in 1 point how much does cinnamon cost per pound

Answer 1

Set up a proportion:


`(3)/(2.40) = (16)/(x)`

The numerator represents the ounces of cinnamon bought, and the denominator represents the cost of the cinnamon.

Cross multiply both fractions:


`3x = 38.4`

Divide both sides by 3 to get x by itself:


`x = 12.8`

Cinnamon will cost $12.80 per pound.
