Quarters: 10
Dimes: 8
Step-by-step explanation:
Constraints
value: 0.25q + 0.10d = 3.30
count: q + d = 18
q = 18 - d
0.25(18-d) + 0.10d = 3.30
4.50-0.25d+0.10d = 3.30
4.50-0.15d = 3.30
-0.15d = -1.20
d = 8
q + d = 18
q + 8 = 18
q = 10
Check:
0.25(10) + 0.10(8) = 3.30
2.5+ 0.80 = 3.30
3.30 = 3.30

21000 people paid for general admission and 6000 paid for reserved seats. This is solved by making 2 equations. Out of 27000 people who were at game, x of them paid for general admission and y for reserved seats, thus
x + y = 27000
As said, daily receipts were 204000$. As reserved seat is 13$, y of them gave 13$ each (y*13$) and x of them gave 6 for general admission(x*6) and those two add up and we get second equation
13y + 6x = 204000.
This can be solved by transforming first equation into x = 27000 - y and then replacing the x in second.
13y + 6*(27000 - y) = 204000
13y + 162000 - 6y = 204000
7y = 42000
y = 6000
x + 6000 = 27000
x = 27000 - 6000 = 21000
