Tickets for admission to a high school football game cost $3 for students and $5 for adults. During one game, $2995 was collected from the sale of 725 tickets. Howmany tickets were sold to students? How many tickets were sold to adults?
N.B. The numbers you gave don't work. I changed the number of tickets sold from 726 to 725.
Let number of students be S
Price of student ticket = $3
Let number of adults be A
Price of adult ticket = $5
A + S = 725 (725 tickets were sold)
5*A + 3*S = 2995 ($2995 collected for all tickets)
Substituting for A = 725 - S into the 2nd equn.
5(725 - S) + 3S = 2995
3625 - 5S + 3S = 2995
630 = 2S
S = 315
A = 725 - 315 = 410
A = 410
