Answer:

y = 2.00 + .10x

9.60

Step-by-step explanation:

Let y = the total fine and x = the number of days the book is overdue.

y = 2.00 + .10x

There is a 2.00 if it is overdue + .10 per day for each day

The cost of 1 overdue book at 12 days overdue

y =2.00 +.10*12

y =2+1.20

  = 3.20

She has 3 books that are 12 days overdue

Multiply this by 3

3.20*3 = 9.60
