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. How much is charged to your debit card?

OpenStudy (hysusonic):

$0.00 because you used cash

OpenStudy (hysusonic):

no first you find much gum is with tax

OpenStudy (anonymous):

Oh! I see, alright. So.. 1.14?

OpenStudy (hysusonic):

yes and now you add that to 34.10 and then you get...

OpenStudy (anonymous):
