Question 688952: Prices for the movie were $4.00 for children and $8.00 for adults. The total amount of ticket sales was $1176. There were 172 tickets sold.How many adults and children bought tickets?
c=children and a=adults
What I tried:
4c+8a=1176
c+a=172
I'm confused on how to solve the number for children tickets I keep getting -40, but I don't think that is right because you can't sell -40 tickets.
