Question

The late fee for library books is $2.00 plus $0.15 each day for a book that is late. If Maria's fee for a lated book is $3.20, write and solve a linear equation to find how many days the book was late.

Answer 1

(0.15 times d) + 2 = how much is due
0.15 times d) + 2 = 3.20
Subtract 2 form both sides
0.15 times d = 1.2
Divide 0.15 form both sides
d=8
Her book was 8 days late
Hope this helps!!!!!!!!!!!!!
