Question 167204: A movie theater charges $8.00 for adults and $5.00 for children. If there were 40 people alltogether and the theater collected $272.00 at the end of the day, how many of them were adults? Answer by Mathtut(3670) (Show Source):
You can put this solution on YOUR website! lets call the number of adults a and the number of children c.

also we know that 8a+5c=272
substituting c's value in the 1st equation into the 2nd equation we get
8a+5(40-a)=272---->lets distribute that left side---->8a+200-5a=272
now lets combine like terms on either side of the equals sign.
so we have
and c=40-a(24)=
