Gina wants to save money for a holiday to bali at the end of the year. she estimates that if would cost her $2200 but she only has 14 weeks of work till then. will she have enough money?

That's a funky problem... :/  I mean it would depend on how much she earns weekly. If she were working 40 hours each week and earning 10$ an hour then yes, she would have enough. Even is she were per say a student on a part time working 30 hours and earning 8$ per hour, she would still have enough.
