Answer:
(a) $ 84.
Explanation:
Given that, the distance between the PA to CA = 3000 miles.
Time of travel, t = 5 days.
The average price of gasoline, r = $ 2.10/ gallon
Cost of meal for one person, c = $ 45/ day
Total number of persons, n = 2 (Mr. and Mrs. Wagner)
(a) The average of van = 75 mpg.
So, to cover 75 miles, the amount of gasoline required = 1 gallon
By using the elementary method, the amount of gasoline required to cover 1 mile = 1/75 gallons.
So, the amount of gasoline required to cover 3000 miles
= (1/75)x 3000= 40 gallons.
Now, cost for gasoline = 40 x 2.10=$84
Hence, the total cost of the gas for the trip is $84.
