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 is gives jack $5 plus $0.50 for each tooth lost. which graph shows the new function?

The new function is and its graph is shown below.

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 .

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.

So, the new function is and its graph is shown below.

You want to leave a 18% tip on a meal that cost $150.

First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.

Second, you need to find out what 18% of your $150 meal cost is.This is always done by multiplying 0.18 by $150.00, or

0.18 x $150.00=$27.00.

So, the amount of tip you are going to leave is $27.00.

This makes the total cost of your meal (to write on your charge slip or other payment)

$150.00 + $27.00 = $177.00.
