5.Postage and handling cost $3.50 no matter how many books are in ordered. Since the Dr. dacres doesn't have to pay sales tax, how much will the total cost be?
Because 4.7 is the "abbreviation" for 4.70 also 4.7 is the simplified version of 4.70 kind of like a fraction you 4 70/100 simplified is 4 7/10 or 4.7.
