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 point)

Answer 1

The total cost to deliver all the pieces of first-class mail can be calculated by multiplying the number of pieces by the cost of each stamp.
52×1010 pieces x $0.55/stamp = $8.36×1010

In scientific notation, this is expressed as 8.36x1010 dollars.

Answer 3

I apologize for the mistake. Let's correct the calculation.

The total cost to deliver all the pieces of first-class mail can be calculated by multiplying the number of pieces by the cost of each stamp.
1.52 × 10^10 pieces x $0.55/stamp = $8.36 × 10^9.

Therefore, the total cost in dollars to deliver all the pieces is 8.36 × 10^9 dollars.

Answer 4

8.36×10^9
