Set up a proportion:

[tex] \frac{3}{2.40} = \frac{16}{x}[/tex]

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

Cross multiply both fractions:

[tex]3x = 38.4[/tex]

Divide both sides by 3 to get x by itself:

[tex]x = 12.8[/tex]

Cinnamon will cost $12.80 per pound.
