jimthompson5910 (jim_thompson5910):
x = # of children y = # of adults 2450 is the total, so x+y = 2450 solve for y to get y = 2450 - x
jimthompson5910 (jim_thompson5910):
$12 for children ----> 12x dollars for all the kids $15 for adults ----> 15y dollars for all the adults total: 12x+15y = 33456
jimthompson5910 (jim_thompson5910):
12x+15y = 33456 12x+15(2450-x) = 33456 ... plug in y = 2450 - x now solve for x
