The total cost to deliver all the pieces of first-class mail can be calculated by multiplying the number of pieces (1.52×1010) by the cost of each stamp ($0.55).

So, the calculation is:
1.52×1010 × $0.55 = $8.36×109

Expressed in scientific notation, the total cost is $8.36×109.

To find the total cost to deliver all the pieces of mail, you need to multiply the number of pieces by the cost of a stamp.

The number of pieces of mail is given as 1.52×10^10.

The cost of a stamp is $0.55.

To find the total cost, you multiply these two numbers:

Total cost = (number of pieces) * (cost of a stamp)
Total cost = 1.52×10^10 * $0.55

To multiply numbers in scientific notation, you can multiply the coefficients and add the exponents.

1.52 * 0.55 = 0.836

10^10 * 10^-2 = 10^(10-2) = 10^8

So, the total cost in dollars to deliver all the pieces is $0.836 * 10^8.

In scientific notation, this can be written as 8.36 x 10^7 dollars.

To calculate the total cost to deliver all the pieces of mail, we multiply the number of pieces by the cost of each stamp.

Given:
Number of pieces of mail = 1.52×10^10
Cost of stamp = $0.55

Multiplying these values, we get:
1.52×10^10 * $0.55 = $8.36×10^9

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