In a given year, about 1.52 x 10^10 pieces of first-class mail are delivered in the U.S if Each price 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 to deliver all the pieces of mail, we need to multiply the number of pieces of mail by the cost of each stamp.
Number of pieces of mail = 1.52 x 10^10
Cost of each stamp = $0.55
Total cost = (1.52 x 10^10) * ($0.55)
To multiply these numbers, we can ignore the units for now and multiply the coefficients.
Total cost = 1.52 * 0.55 * 10^10
Multiply the coefficients: 1.52 * 0.55 = 0.836
The exponent for 10 is the sum of the exponents of the numbers being multiplied: 10^10
So the total cost in scientific notation would be 8.36 x 10^9 dollars.
