To find the total cost in dollars to deliver all the pieces of mail, we multiply the number of pieces (1.5×10^10) by the cost of each piece (55 cents).
First, convert 55 cents to dollars:
55 cents = 55/100 = 0.55 dollars
Now, multiply the number of pieces by the cost of each piece:
1.5×10^10 * 0.55 = 8.25×10^9 dollars
The total cost to deliver all the pieces of mail is 8.25×10^9 dollars.
