By: Danielle Kelly

My Real World Problem  Danielle went to Aeropostale and got 7 cami’s for each how much did she spend.

The Equation  My equation is: Y= 17.50x or f(x)= 17.50x X= the number of cami’s Y= the total cost 17.50*7 =? Cami

Independent and Dependent  My independent variable is the x which is the number of cami’s  My dependent variable is y which is the total cost  Y depends on x  The total cost depends on the number of cami’s.

Table of Values x17.50xy(x,y) (1)17.50(1,17.50) (2)35.00(2,35.00) (3)52.50(3,52.50) (4)70.00(4,70.00) (5)87.50(5,87.50) (6)105.00(6,105.00) (7)122.50(7,122.50)

Domain and Range  Domain is the x values  Range is the y values  My domain is (1,2,3,4,5,6,7)  My Range is (17.50,35,52.50,70,87.50,105,122.50) R A DOMAIN G E

Is it Continues or Discrete  It is Discrete graph because my data only contains points.  You can’t buy 1½ you can only purchase shirts by 1,2,3 and so on. So we wont use numbers between 1and 2.

Is it a Function  Yes because my x values don’t repeat. X

Cami’s Ticket Graph

Soooo….  Depending on the amount of shirts Danielle wanted to buy, it could cost for just one shirt for or getting 7 shirts it could cost not including tax. I wonder how much that would be well that problem is to figure out next time.
