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:

$\frac{3}{2.40} = \frac{16}{x}$

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.
