Lemme see
9 + 16 = 25 sure enough
2.5 * 9 + 3.25 * 16 = 74.5
which you could have done.
If you are stuck, ask for help. If you need an answer checked, first check it.

The answer is 9.
If the hamburgers are $2.50, and the chicken strips $3.25, then,
$2.50 * 9 + $3.25 * 16 = $74.50
If the hamburgers are $2.50, and the chicken strips $3.25, then,
$2.50 * 9 + $3.25 * 16 = $74.50
