Nina has some money saved for a vacation she has planned. the vacation will cost a total of $1600. she will put $150 every week into her account to pay for the vacation. she will hav enough money for the vacation in 8 weeks. if nina was able to save $200 a week instead of $159 a week, how many fewer weeks would it take her to save money for the vacation

2 fewer weeks

Step-by-step explanation:

The vacation will cost a total of $1600

She saves $150 per week.

So, she saves in 8 weeks =

                                          =

Since we are given that she will have enough money after 8 weeks

This means she already had 1600-1200 = 400 initially

This means she need to save 1200  and she already has 400

If she saves $200 per week

So, she saves in 1200 in weeks =

                                                     =

So, it will take 6 weeks to save 1200 if she saves 200 per week

So, no. of fewer weeks it would take o save money for the vacation :

= 8-6

=2

Hence it will take 2 fewer weeks to save money for the vacation.
