Rex budgeted $120 a month for eating out. At an estimated $8 per meal,

that allows him 15 meals per month. He would like to eat 24 meals out
per month. How much more would he have to budget?
a. $5
b. $192
c. $9
d. $72

Rex is currently budgeted for 15 meals, which means he is spending $120 / 15 = $8 per meal.

To eat 24 meals out per month, he would need to budget 24 * $8 = $192.
Therefore, the answer is b. $192 - $120 = $72 more that he would have to budget.
