1. Tanning for Math! By Caroline Purtle Math 6 9-29-10

2. 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??

3. EQUATION 1,000-(50x-150)= Y

4. Variables Independent- The number of tans. Dependent- The cost of the bill. The cost of the bill depends on the number of tans.

5. IS THIS A FUNCTION? Yes because It passes the vertical line test!

6. 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.

7. Equation: 1,000-(50x-150) Function notation: f(x)=1,000-(50x-150) xProblemy(x,y) 11000-(50*1-150)-1,100(1,-1,000) 21000-(50*2-150)-1,150(2,-1,050) 31000-(50*3-150)-1,000(3,-1,000) 41000-(50*4-150)-950(4,-950) 51000-(50*5-150)-900(5,-900)

8. Here is the Graph for our monthly expenses!

9. THE END. I’m in debt.
