How do you translate the following word problem into an algebraic equation: A cell phone company is offering its custumers the following deal. You can buy a new cell phone for $60 and pay a monthly flat rate of $40 per month for unlimited calls. How much money will this deal cost you after 9 months?

Let x = cost after 9 months. Let y = cost of phone.
x = y + (r · t)
y = $60.00
r = monthly rate of $40.00
t = time period of 9 months
The months cancel, leaving dollars.
