In a given year, about 1.52×1010 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

1 answer

To find the total cost to deliver all pieces of mail, we multiply the number of pieces (1.52×10^10) by the cost per stamp ($0.55):

Total cost = (1.52×10^10) * ($0.55)

Let's calculate this:

Total cost = 8.36×10^9 dollars
