The graph below shows the speed of a school bus making its afternoon round. Notice that the bus leaves the school and speeds up to 45 kilometers per hour until it reaches the neighborhood where the students are to disembark. In the neighborhood, the bus stops and starts until all the students have left the bus. The bus then picks up speed and returns to its garage for the night.
How do you think the trip of a roller coaster at an amusement park could be represented? Be sure to indicate the elapsed time and the rate on your axes.
The roller coaster will go slowly up the first long hill and will descend rapidly. From then on its speed will fluctuate until it stops.
Charlene started the week with no money, but found $5.00 in her coat pocket on Monday. On Friday after school she spent $3.00 for a paperback book, leaving her with a balance of $2.00. On Sunday she earned $10.00 by doing yard work for her neighbor. The balance on Sunday was then $12.00. On day 8, Monday, Charlene’s friend, Sharee, called and asked if she wanted to go to the music store to buy the latest ‘nSync CD. Since the CD cost $15.00 and Charlene only had $12.00, Sharee offered to loan her the money. Charlene took the loan, which left her with a negative cash balance of $3.00. On day 11, Thursday, Charlene earned another $10.00 by doing yard work and had $7.00 left after paying her $3.00 debt to Sharee. On day 14, Sunday, Charlene earned another $8.00, giving her a new cash balance of $15.00. On day 16, Tuesday, Charlene went to the mall with Sharee and spent $9.00 for a sparkly pen and writing notebook. Her final cash balance on day 16 was $6.00.
