Answer:

19 $20 bills

Explanation:

Let's assume the number of $20 bills in the cash drawer is "x."

The value of the $20 bills can be calculated by multiplying the number of bills by the denomination:

Value of $20 bills = 20 * x

Similarly, the value of the $5 bills can be calculated by multiplying the number of bills by the denomination:

Value of $5 bills = 5 * (50 - x) (since there are a total of 50 bills)

According to the given information, the total value of all the bills is $535:

Value of $20 bills + Value of $5 bills = $535

Substituting the expressions for the values:

20 * x + 5 * (50 - x) = 535

Simplifying the equation:

20x + 250 - 5x = 535

Combining like terms:

15x + 250 = 535

Subtracting 250 from both sides:

15x = 285

Dividing both sides by 15:

x = 19

Therefore, there are 19 $20 bills in the cash drawer.
