Question

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?

Answers

  1. Answer:
    $5.25
    Step-by-step explanation:
    Cost of gasoline
    • 9.25 gallons at $3.15 per gallon:
    ⇒ 9.25 × $3.15 = $29.1375
    Cost of gum
    $1.10 plus 4% food tax:
    ⇒ $1.10 × 1.04 = $1.144
    Total cost of purchases
    Gasoline + gum + Windshield wiper fluid
    ⇒ $29.1375 + $1.144 + $4.97 = $35.2515 = $35.25 (nearest cent)
    If $30.00 was paid by cash and the rest was paid for by debit card:
    Debit card charge = $35.25 – $30.00 = $5.25

  2. Answer:
    • $ 5.25 is charged to debit card

    Subtract $30 paid in cash:
    • 35.25 – 30 =
    • 5.25
