How much change will John get back from 5$ if he buys 2 note books that cost $1.80 each

Answer:
A. $1.40
Step-by-step explanation:
First, we need to figure out how much two notebooks cost together.
1.80+1.80=3.60
John will owe $3.60 for the two notebooks.
He pays with $5
5.00-3.60=1.40
John will get back $1.40 in change
