Answer:
Question 1: 37 mpg
Question 2: $128.16
Step-by-step explanation:
1.
Miles Per Gallon would be total number of miles divided by total gallons used. So we have:
MPG = [tex]\frac{682}{18.6}=36.66[/tex]
rounded to the nearest mpg, we have 37 mpg
2.
To get "number of gallons used" we can divide total miles (1224) by miles per gallon (34).
Number of gallons used = [tex]\frac{1224}{34}=36[/tex] gallons
It cost $3.56 per gallons, so 36 gallons would cost  [tex]3.56*36=128.16[/tex] dollars
Option C is right, $128.16.
