the schools football team makes it to the championship and the athletic department decides to change the price of tickets for th
e final game. adult ticket prices have been lowered to $5.00 and student tickets now cost $3.00. at the championship game. 1142 tickets are sold. total ticket sales equaled $4326.00 . let a equal the number of adult tickets sold, and let s equal the number of student tickets sold.
So 5a=cost of adults 3s=cost of students a+s=1142 5a+3s=4326
a+s=1142 subtract s from both sdies a=1142-s subsitute 1142-s for a 5(1142-s)+3s=4326 5710-5s+3s=4326 5710-2s=4326 subtract 5710 from both swides -2s=4326-5710 -2s=-1384 dividee both sides by 2 -s=-692 multiply -1 s=692 692 students subsittue
