Answer:

A. t(n) = 20 + 60n

Step-by-step explanation:

Since Rob already had $20, the equation should have +20 to represent the money he already had.

60n can represent how much money Rob gets after washing windows, since he earned $60 from each weekend he washed windows.

So, A is the correct answer, t(n) = 20 + 60n
