5. you are making your weekly mean plans and are working with the following constraints: it costs $8 to go out to dinner. it costs $5 to go out to lunch. you want to go out to dinner at least as many times as you go out to lunch. you can spend at most $42.
what is the greatest number of meals you can eat out?
3
4
5
6

The correct answer for this question would be option D.6. Given that per dinner, you can spend $8 and per lunch is $5. Given that you can spend at most $42, you can only eat out 6 times. 3 times for lunch and 3 times for dinner.
Since 8 times 4 would be $24 in total, and 5 x 3 would be $15 in total, so the overall would be $39. Hope this is the answer that you are looking for.
