Multiply the amount she puts in the account every week by the number of weeks (w) and add that to what she already has saved:
20w + 600 >= 2000
Answer: 10 weeks
2,000 ÷ 200 = [tex]w[/tex]
[tex]w[/tex] = 10 because 2,000 ÷ 10 = 200
Martha must put $20 in her account for 10 weeks.
Hope this helps you!
