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?

Answer 1

Answer:

• $ 6.62 is charged to debit card

Step-by-step explanation:

Total amount of purchase is:

• 9.25*3.15 + 1.10 + 4.97 =
• 35.21  (rounded)

Add 4% tax:

• 35.21*1.04 =
• 36.62 (rounded)

Subtract $30 paid in cash:

• 36.62 - 30 =
• 6.62

Answer 2

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
