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. Answer by solver91311(24713) (Show Source):
There are at least 4 ways to solve this, all of which give you the same answer and none of which give you negative numbers for either of the variables.
Substitution
Elimination method
Multiply the 2nd equation by -8
Add the two equations, term by term
