An adult’s dinner costs $7. A family of 3 adults and 2 children pays $31 for their dinners. 1. How much does a child’s dinner cost?

2. If you were given $48 what combinations of adults and children could you bring to dinner? Provide at least two different examples and show your work.

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
