At the amusement park,each student is given $16 for food. This covers the cost for 2 meals plus $4 for snacks. How much money does the schools expect each student to spend per meal?

The school expects each student to spend $6 for each meal.

If you take the initial $16 and subtract the money for snacks, so 16-4, you end up with $12. Since the students must purchase 2 meals they will still have enough to spend $6 per meal.
