This problem represents a system of equations word problem. We will need to write two equations and then solve the system of equations.

Let's first define our variables:

Let W = Wednesday night's income
Let S = Sunday night's income

Since we know that the two games together produced \$5070.50, we can write the first equation as:

W+S = 5070.50

We also know that Wednesdays game produced 1095.50 less than Sunday's game, so...

W = S-1095.50

To summarize, here are the two equations:
W+S = 5070.50
W = S-1095.50

Now we must solve the system of equations.

Since one of the variables is solved, I will use the substitution method. I will substitute
W = S-1095.50 into the first equation.

W+S = 5070.50
S-1095.50 +S = 5070.50
2s - 1095.50 = 5070.50 - combine like terms

Now add 1095.50 to both sides:
2s - 1095.50 +1095.50 = 5070.50 + 1095.50
2s = 6166

Divide both sides by 2:
2s/2 = 6166/2
s = 3083

Now we know Sunday's game produced 3083.00

Substitute to find Wednesday's game earnings.
W = s-1095.50
W = 3083.00-1095.50
W = 1987.50

Sunday's game earnings were \$3083.00
Wednesday's game earnings were \$1987.50
