Question 3.
As President of the Debate Team at your school, you have a variety of responsibilities and duties. One of which includes finding the most economical way of transporting the team to the various local competitions. ( The school has given you a very limited budget so you have to spend it wisely.) It has been decided at the last Debate Team practice that the best ways to travel are by taxi or school bus. You've done some research and found out that taxi's in the city can only carry five passengers at a time and charge a rate of $1.25/km, while the school board can provide a bus that will carry everybody at once at $3.00/km plus service charge of $45.00. (Service charge looks after the fuel and driver costs.) You now have to make a decision and present it to the team! There are 30 people on the team.
