To represent the inequality, let us define some variables first:
lets say 'w' represents the greatest number of weekly withdrawals:
Elise has budget of $800 in her checking account:
If she withdraws $50 each week then in 'w' number of weeks she has withdrawn [tex]50 \times x[/tex] dollars.
The amount left in her checking account is given by:
[tex]800-50\times x[/tex]
Now, she needs to have at least $200 available at the end of summer.
Which means:
[tex]800-50\times x\geq 200[/tex]
The inequality [tex]800-50x\geq 200[/tex] can be used to determine the greatest number of weekly withdrawals.
