A cellphone company charges $50 per month to their existing customers for unlimited text messaging. A new customer has to pay a one-time enrollment fee of $74 in addition to the regular monthly fee. Let x represent the number of months and y represent the amount of money an existing customer has paid for unlimited text messaging over that time to write an equation for the given context.
y = 50 x + 74
