icang [17]

Answer:

  • Britta paid more per kilometer driven

Explanation:

<u>1) Britta:</u>

  • Distance traveled: 1,250 Km
  • Gasoline used: 209 liter
  • Gasoline price: 1.23 euros / liter

Cost per km = total cost of gasoline / distance traveled

Cost per km = gasoline used × gasoline price / distance traveled

Cost per km = 209 liter × 1.14 (euro / liter) / 1,250 km =  0.19 euro / km

<u>2) Pierce:</u>

  • Distance traveled: 1,405 km
  • Gasoline used: 175 liter
  • Gasoline price = 1.23 euros / liter

Cost per km = 175 liter × 1.23 (euro / liter) / 1,405 km =  0.15 euro / km

<u>3) Comparison:</u>

  • 0.19 > 0.15 ⇒ Britta paid more per kilometer driven
