Total cost for 2 months is 20 + 30 + 30.
so it would be $80 for two months then?
Right.
thank you that means she will be only able to get two months with her $90 then?
or maybe two and a half months with her $90>?
Services don't sell parts of months. Yes her $90 buys her the phone and two months service. She'll have $10 left over.
thank you
You're welcome.
