Jacy has a choice of cell phone plans. Plan A is to pay $260 for the phone and then pay $70 a month for service. Plan B is to get the phone for free and pay $82 a month for service. Find the equation to represent Plan A.

• y = 260x

• y = 260 - 70x

• y = 70x + 260

• y = 70x

Jacy has a choice of cell phone plans. Plan A is to pay $260 for the phone and then pay $70 a month for service. Plan B is to get the phone for free and pay $82 a month for service. Find the equation to represent Plan B.

• y = 82

• y = -82x

• y = 260 + 82x

• y = 82x
