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
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.
