Tanning for Math!

By Caroline PurtleMath 69-29-10

My Problem:• Snooki has a tanning salon named

Tan Band. The bills to keep it open cost $1,000 a month. If each tan cost $50 per person and she has $150 more to pay her employees with, how will she make at the end of the month??

EQUATION

1,000-(50x-150)= Y

Variables

• Independent- The number of tans.

• Dependent- The cost of the bill.

The cost of the bill depends on the number of tans.

IS THIS A FUNCTION?

Yes because It passes the vertical line test!

Definition

Domain:• The set of all possible input

values of relation or function

Range:• The y-value

Is the domain continuous or discrete?Continuous because there is no stopping point it can go on forever.

Equation: 1,000-(50x-150)Function notation: f(x)=1,000-(50x-150)

x Problem y (x,y)

1 1000-(50*1-150) -1,100 (1,-1,000)

2 1000-(50*2-150) -1,150 (2,-1,050)

3 1000-(50*3-150) -1,000 (3,-1,000)

4 1000-(50*4-150) -950 (4,-950)

5 1000-(50*5-150) -900 (5,-900)

Here is the Graph for our monthly expenses!
