Part A)
The mileage for city use is 16.81 L per 100 km. In other words, if you traveled 100 km in the city, then you use up 16.81 liters of gas.
We can set up this equation
16.81 liters = 100 km
Multiply both sides by 3 so that the "100 km" turns into "300 km"
16.81 liters = 100 km
3*16.81 liters = 3*100 km
50.43 liters = 300 km
<h3>Answer: 50.43 liters</h3>
==================================
Part B)
Multiply the answer in part A by the cost per liter, which is $1.01
Total cost = (cost per liter)*(number of liters)
Total cost = (1.01)*(50.43)
Total cost = 50.9343
Total cost = 50.93
<h3>Answer: 50.93 dollars</h3>
==================================
Part C)
We're effectively repeating part A, but now we're using the highway mileage value.
11.8 liters = 100 km
3*11.8 liters = 3*100 km
35.4 liters = 300 km
<h3>Answer: 35.4 liters</h3>
==================================
Part D)
We follow similar steps as we did in part B. Use the value in part C to get
Total cost = (cost per liter)*(number of liters)
Total cost = (1.01)*(35.4)
Total cost = 35.754
Total cost = 35.75
<h3>Answer: 35.75 dollars</h3>
==================================
Part E)
Subtract the results of parts B and D
50.93 - 35.75 = 15.18
<h3>Answer: 15.18 dollars</h3>
