In a given year, about 1.52 times 10^10 pieces of first-class mail are delivered in the U.S. If each piece of mail carries a stamp costing $0.55, what is the total cost in dollars to deliver all the pieces? Write the answer in scientific notation, expressed to the exact decimal place.
To find the total cost, we multiply the number of pieces of mail by the cost of each stamp.
Total cost = (1.52 x 10^10) * $0.55
Total cost = 8.36 x 10^9 dollars
Therefore, the total cost to deliver all the pieces of mail is $8.36 x 10^9.
