- Paul wants to figure out the fuel consumption of his new SUV in the city. He made
sure the tank was close to empty and then he filled it up. The odometer read 5,600
when he filled it up and read 6,096 when he was empty again. He has a 75 L tank.
The cost of fuel is $.97 per L.

a. What is Paul's estimated fuel consumption for his SUV in L/100 km?

b. How much does it cost Paul to fill his tank at the listed gas price?

c. Paul usually drives at least 350 km per week. How much would this cost
him? (you will need to do a ratio)

[tex]\text{Fuel consumption} = \dfrac{\text{75 L}}{\text{496 km}} \times \dfrac{\text{ 100 km}}{\text{100 km}} = \dfrac{\text{15.1 L}}{\text{100 km}}[/tex]

(b) Cost to fill tank

[tex]\text{Cost} = \text{75 L} \times \dfrac{\text{\$0.97}}{\text{1 L}} = \$72.75[/tex]

(c) Cost per week

i. Calculate the volume of gasoline

[tex]\text{Volume} = \text{350 km} \times \dfrac{\text{75 L}}{\text{496 km}} = \text{52.9 L}[/tex]

ii. Calculate its cost

[tex]\text{Cost} = \text{52.9 L} \times \dfrac{\text{\$0.97}}{\text{1 L}} = \$51.34[/tex]
