Respuesta :

the answer to the first question is C. 37 mpg 

The answer to the second question is C. 128.16 

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.
