Question

The late fee for library books is 2.00 plus 15c each day for a book that is late if Maria fee for a late book was 3.20 write and solve a linear equation to find how days late the book was

Answer 1

8 days

Explanation:

Let x be the amount of days the book is late.

The equation we can set up is:

200+15x=320 (note that we need to convert $2.00 and $3.20 to cents)

Subtract 200 from both sides

15x=120

Divide both sides by 15

x=8

It was late by 8 days.
