For this case, the first thing we must do is find the unit cost.

We have then:

\(C = \frac {68.64} {4}\\C = 17.16\)

We now look for the number of hats that can be purchased with $ 154.44.

We have then:

\(N = \frac {154.44} {17.16}\\N = 9\)

Therefore, you can buy 9 hats with $ 154.44.

Answer:

Melissa sells 9 hats.

C. 9
