a) 500 -25x ≥ 200 b) 12 weeks
1) Gathering the data
$500
At least : ≥ 200
Withdrawal = -25
A) Since she wants at least 200 in the account, and the summer has 12 weeks, We can write this inequality:
500 - 25x ≥ 200
B) To find how many weeks we need to solve an equation
500-25x= 200
-25x = 200 -500
-25x = -300
25x = 300
x=12
Under these conditions, 12 weeks in the 13th week she won't be able to keep at least $200 in her account with these weekly withdrawals
