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.
