Question

Jenny has saved $600 from her summer job. During the school year, she withdraws $20 from her account every week for her daily expenses. She wants to keep more than $300 in the account for college. The number of weeks, w, that Jenny can withdraw money from her account is represented by the inequality 600 − 20w > 300. How many weeks can Jenny continue to withdraw $20 from her account?

14
17
20
22

Answer 1

600 - 20w > 300

-20w > 300 - 600

-20w > - 300

20w < 300

w < 300/20

w < 15

Therefore, Jenny can withdraw $20 from her account for 14 weeks
