Homework Help: math

Posted by Megan Brown on Monday, January 31, 2011 at 11:45am.

A charity fund-raiser consisted of a spaghetti dinner where a total of 387 people were fed. They charged $6.80 for adults and children were half price. If they took in $2444.60, find out how many adults and how many children attended the dinner. I have no idea how to solve this problem. I would appreciated any help I can get.

n = number of adults
6.80n = value of adults
387 - n = number of children
3.40(387 - n) = value of children

6.80n + 3.40(387 - n) = 2444.60

Solve for n = number of adults
387 - n = number of children
