Question:
The tooth fairy brings Jack $5 plus $1 for each tooth that he loses. After Jack loses a few teeth, the tooth fairy decides that he is paying too much money for teeth. He now gives Jack $5 plus $0.50 for each tooth lost. Which graph shows the new function?
Answer & Step-by-step explanation:
Let the number of tooth = x and the cost of teeth = y (in dollars).
Tooth fairy charges $1 for each tooth with extra charge of $5.
So, the cost of the teeth is y=x+5.
Now, the tooth fairy charges $0.5 for each tooth with extra charge of $5.
Thus, the new cost of the teeth is given by.
y=0.5x+5
So, the new function is y=0.5x+5 and its graph is shown below.
