1. Sample Question Four members of the Johnson family took a trip from Pittsburgh to Harrisburg, a distance of 221 miles. It took them 4 hours and 15 minutes to make the trip. The car required 13 gallons of gasoline at $1.25 per gallon. The turnpike toll was $6.50, and they spent $12.84 for food. What was the average cost per mile based on the total expenses of gas, food and tolls for this trip?

2. The Work 1) $1.25 X 13 gal = $16.25 2) $16.25 + $6.50 + $12.84 = $35.59 3) $35.59  221 mi  $0.1610407 4) $0.16 per mile

3. The Explanation 1) I multiplied the price of gas and the number of gallons TO GET the total cost of gas. 2) I added the cost of gas, food and tolls together TO FIND the total cost of the trip. 3) I divided the total cost of the trip by the number of miles and I FOUND the cost per mile. 4) SINCE I had many decimal places, I rounded to the hundredth BECAUSE the answer was in terms of money. My answer is 16 cents per mile.

4. The Final Product Work 1) $1.25 X 13 gal = $16.25 2) $16.25 + $12.84 + $6.50 = $35.59 3) $35.59  221mi  $0.161041 4) $0.16 per mile Explanation 1) I multiplied the price of gas and the number of gallons TO GET the total cost of gas. 2) I added the cost of gas, food and tolls together TO FIND the total cost of the trip. 3) I divided the total cost of the trip by the number of miles and I FOUND the cost per mile. 4) SINCE I had many decimal places, I rounded to the hundredth BECAUSE I wanted money.
