Explanation / Answer

1)

total population= 11435798

1.5 car per persol

total car in million = 1.5*11435798 /106 = 17.1536 million = 17 million (option a)

2)

total car = 1.5*11435798

each car is driven 10000 miles

total driving in billion miles = 1.5*11435798*10000/109 = 171.53 (option c)

3)

total billion mile = 171.53

fuel cunsumption =22 mile per gallon

total fuel in billion gallon = 171.53/22=7.79 = 7.8 billion gallon (option b)

if we increase 5 cents = 0.05 doller

total collectoin - 0.05*7.8 = 0.39 billion = 0.39*1000 = 390 million (option d)
