Fine=$2+$0.25 (d-1), d= number of days
3.25=2+0.25*(d-1)
1.25=0.25 (d-1)
5=d-1
d=6 days.

first day 2 Plus additional days 0.25. How many additional days? We don't know, so we assign the variable x to the additional days. Now we get:
2+0.25x = 3.25 subtract 2 on both sides:
0.25x = 1.25 divide both sides by 0.25. On the left 0.25 multiplying and 0.25 dividing cancel each other and you have just the x left. On the right, divide and get your answer.
