Question 599674
Admission to a baseball game is $3.00 for general admission and $6.00 for reserved seats.
 The receipts were $3561.00 for 868 paid admissions.
 how many of each ticket were sold?
:
The easiest way to solve this is with a system of equations
:
Let g = no. of general admission tickets
Let r = no. of reserve tickets
:
The total admissions equation
g + r = 868
g = (868-r); use this form for substitution
:
The total receipts equation
3g + 6r = 3561
substitute g with (868-r)
3(868-r) + 6r = 3561
2604 - 3r + 6r = 3561
-3r + 6r = 3561 - 2604
3r = 957
r = 957/3
r = 319 reserve seat
then
868 - 319 = 549 general admission seats

Confirm this in the total receipts equation
