The late fee for library books is $2.00 plus 15¢ each day for a book that is late. If Maria's fee for a late book was $3.20, write and solve a linear equation to find how many days late the book was.

8 days

Step-by-step explanation:

According to the information given, you can write an equation that states that 15¢ multiply for the number of days that the book was late plus $2 is equal to $3.20:

0.15x+2 = 3.20

x = number of days that the book was late

Now, you have to solve for x:

0.15x = 3.20-2

0.15x = 1.20

x = 1.20/0.15

x = 8

The book was 8 days late.

the book was late for 8 days

have a good day
