you purchase 9.25 gallons of gasoline at $3.15/gallon. you also buy gum ($1.10) and windshield wiper fluid ($4.97). the state has a food tax of 4% and you give the clerk $30.00 cash. you pay the rest with your debit card. how much is charged to your debit card?

a) $35.21
b) $5.21
c) $35.25
d) $5.25

It would be easier if we list all of the cost involved in the problem statement and add it all up to determine the total cost. We do as follows:

gasoline         29.14
gum                   1.10
wiper fluid        4.97
food tax           0.044

total                 35.254
-                       30.00

                           5.254 <OPTION D

Idon’t know but you’ll figure it out
