Question

the schools football team makes it to the championship and the athletic department decides to change the price of tickets for the 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.

Answer 1

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

a+692=1142
subtract 692
a=450

s=692
a=450
