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

Answer:

14 weeks

Step-by-step explanation:

Given : The number of weeks, w, that Jenny can withdraw money from her account is represented by the inequality 600 − 20w > 300.

To Find: How many weeks can Jenny continue to withdraw $20 from her account?

Solution:

Expression: 600 − 20w > 300.

Now we are supposed to find for how many weeks can Jenny continue to withdraw $20 from her account.

So, $600 -20w > 300$

$-20w > 300-600$

$-20w <-300$

$20w< 300$

$w<\frac{300}{20}$

$w<15$

Thus jenny can continue for less than 15 weeks .

So, Option A is correct.

Hence Jenny can continue for 14 weeks to withdraw $20 from her account.
