A customer is withdrawing $890 and wants as many $50 bills as possible. How many $50 bills should the Teller give her?

890 / 50 = ?

18

To determine the number of $50 bills the teller should give, we need to divide the total amount of money the customer wants to withdraw by the denomination of the bills, which is $50.

So, to find the number of $50 bills, we can use the following formula:
Number of $50 bills = Total amount / Denomination

In this case, the total amount the customer wants to withdraw is $890, and the denomination of the bills is $50. Plugging in these values into the formula:

Number of $50 bills = 890 / 50

Simplifying this calculation, we have:

Number of $50 bills = 17.8

Since the customer cannot have fractional bills, we need to round down to the nearest whole number. Therefore, the teller should give the customer 17 $50 bills.
