Let X = free tax returns

Y = $35 tax returns

Solve for Y:

0X + 35Y = 7245

35Y = 7245

Y = 7245 / 35

Y = 207 Tax Returns at $35

She donates $2 for every tax return

Now we can solve for X:

2 (x+y) = 1242

2 (x + 207) = 1242

2x + 414 = 1242

2x = 828

x = 828 / 2

x = 414 Free returns.

She did 414 returns for free and 207 returns for $35.
