Which of the equations below represents the third step of the solution process?
Step 1: 3(cx - 7) -3x = -15
Step 2: 6x - 21 - 3x = -15
Step 3:     ?  ?  ?  ?
Step 4: 3x = 6
Step 5: x = 2

• 3x + 21 = -15
• 3x = -36
• 21 - 3x = -15
• 3x - 21 = -15

Xbox Live is promoting a new game plan in which the initial cost is $64.99 with a $1.50 charge for each day you play. The relationship for the total cost can be expressed by the function f(x) = 1.50x + 64.99, where x represents the number of days you play.  Which statement below is a correct representation of the slope?  

• The initial cost that will be charged is $64.99.
• There is $1.50 cost per day that xbox live will charge.
• The number of days you play will be unlimited.
• If you play 10 days it will cost you $74.99.
