The City Zoo has different admission prices for adults and children. When three adults and two children went to the zoo, the bill was $80.88. If two adults and three children got in for $76.47, then what is the price of an adult's ticket and what is the price of a child's ticket?

Thanks

**Reiny**, Sunday, December 2, 2012 at 9:50pmadult ticket --- $x

child ticke ---- $y

3x + 2y = 80.88

2x + 3y = 76.47

1st times 3 ---> 9x + 6y = 242.64

2nd times 2 --> 4x + 6y = 152.94

subtract them:

5x = 89.7

x = 17.94

in 1st

3(17.94) + 2y = 80.88

2y = 27.06

y = 13.53

adult ticket is $17.94

child's ticket is 13.53
