## Pre-Algebra Tutorial

#### Intro

This is a practical exercise to improve math skills and get students to think about applying math to problems they will encounter in life.

#### Sample Problem

You just bought your first car and want to visit your girlfriend who lives 50 miles away. You were paid from your part-time job and have 30 dollars. Your car gets 30 miles per gallon. Gas costs \$2.20/gal. You also want to treat your girlfriend to a movie for \$7.50 and lunch at McDonald’s for \$6.25. Do you have enough money?

#### Solution

Total miles: (2 x 50) = 100 miles

miles/gallon:30 miles

total gallons needed: 100 miles divided by 30/mpg=3.3 gallons

cost of gas: 3.3 gallons x \$2.20=\$7.26

cost of movie: (2 x 7.50)=\$15

cost of lunch: (2 x 6.25)=\$12.50

Total cost of trip: (\$7.26+\$15+\$12.50)=\$34.76

Answer: You’d better come up with another 5 bucks.

Extra credit: What should you always bring with you?

Answer: An empty gas canister.
