# The late fee for library books is $2.00 plus 15 cents each day for a book that is late. If Monica's late fee is$2.75, how do you write and solve a linear equation to find how many days late her book is?

LF=$2.00+$0.15Dto Linear equation

Monica's book is $5$ days late.

#### Explanation:

Late fee consists of $2.00 fine plus $0.15D fee or each day:

LF=$2.00+$0.15Dto Linear equation

Then:

$2.75=$2.00+$0.15D $2.75-$2.00=$0.15D

$0.75=$0.15D

(cancel($0.75)(5))/cancel($0.15)=D

$5 = D$
