To answer this question you will want to know how much money she started with.
If she saves $150 a week for 8 weeks, this is 150 x 8 or $1200. This means she started with $400.
If she saves $200 a week beginning with $400, this will take her 6 weeks of saving. (-$1600 -$400 = $1200; $1200/$200 = 6 weeks of saving).

Answer:
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 = [tex]150 \times 8[/tex]
= [tex]1200[/tex]
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 = [tex]\frac{1200}{200}[/tex]
= [tex]6[/tex]
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.
