Mr. and Mrs. Wagner are getting ready to drive across the USA from Philadelphia, PA to Los Angeles, CA in five days. The distance is approximately 3,000 miles. The average price of gasoline is about $2.10 per gallon. They plan to stay in a hotel for four nights and budget the cost of meals be about $45 per day per person.

(a) $ 84.

Step-by-step 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.
