Answer: they produce 50,000,000 bills
Explanation:
Let's start by converting $5.5 million to cents, since the cost to produce each bill is given in cents. $5.5 million is equal to 5,500,000 dollars. To convert dollars to cents, we multiply by 100. So, $5.5 million is equal to 550,000,000 cents.
Next, we divide the total production costs (550,000,000 cents) by the cost to produce each bill (11 cents):
550,000,000 cents ÷ 11 cents = 50,000,000 bills
Therefore, when the U.S. Mint pays more than $5.5 million in production costs for $5 bills, they produce 50,000,000 bills.
