2. Mariah and Natasha are going skating with three other friends. If tickets cost $5.00 a piece, then how much will it cost for all of them to go.

3. y= 5.00x or f(x)= 5.00x x= The number of skating tickets y= The total cost

4. The independent variable is x, the number of skating tickets. The dependent variable is y, the total cost. Since y depends on x, the total cost depends on the number of skating tickets.

5. x5.00xy(x,y) 15.00(1)5.00(1,5.00) 25.00(2)10.00(2,10.00) 35.00(3)15.00(3,15.00) 45.00(4)20.00(4,20.00) 55.00(5)25.00(5,25.00)

6. The domain is D:{1,2,3,4,5} The range is R:{5.00,10.00,15.00,20.00,25.00}

7. It is discrete, because it only contains points.

8. Yes, because my x values do not repeat.

10. It would cost Mariah, Natasha, and there three other friends $25.00 all together, without extra drinks or food.
