Therefore the inequality is x≤11

and maximum I can withdraw 11 bills.

Step-by-step explanation:

Given ,

Current balance $320

Minimum balance $100

I could spent =$(320-100) = $220

Let the number of bills be x.

Total amount of x bills = $20x

According to the problem,

20x≤ 220

⇔x ≤ [tex]\frac{220}{20}[/tex]

⇔x≤11

Therefore the inequality is x≤11

and maximum I can withdraw 11 bills.
