Dan pays $60 per month for internet and paid a sign up fee of $90.  He has already paid a total of $450. (A) Write an equation to represent the situation. (B) How many months has he had internet?

• A: 60 + 90x = 450, B: 6 months
• A: 60x + 90 = 450, B: 6 months

• A: 60 + 90x = 450, B: 4 months

Solve for y.
-3x + y = 12

• y = 3x + 12
• y = 9x
• y = 12 - 3x
• y = 15x
