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.
To find the total cost to deliver all the pieces of mail, we can multiply the number of pieces of mail by the cost of each stamp.
Total cost = Number of mail pieces × Cost of each stamp
Total cost = (1.52 × 10¹⁰) × $0.55
Calculating the product:
Total cost = 1.52 × 10¹⁰ × 0.55
= 8.36 × 10⁹
The total cost to deliver all the pieces of mail is $8.36 × 10⁹.
To find the total cost to deliver all the pieces of first class mail, we can multiply the number of pieces of mail by the cost of each stamp.
Total cost = Number of pieces × Cost per stamp
Given:
Number of pieces of mail = 1.52 × 10¹⁰
Cost per stamp = $0.55
Plugging in the values into the formula:
Total cost = 1.52 × 10¹⁰ × $0.55
To multiply these two numbers in scientific notation, we multiply the coefficients and add the exponents:
Total cost = 1.52 × 0.55 × 10¹⁰
Calculating the product:
Total cost = 0.836 × 10¹⁰
To express this in scientific notation to the exact decimal place, we move the decimal point one place to the right:
Total cost = 8.36 × 10⁹ dollars
Therefore, the total cost in dollars to deliver all the pieces of mail is 8.36 × 10⁹ dollars.
To find the total cost in dollars to deliver all the pieces of mail, we need to multiply the number of pieces of mail by the cost of a stamp.
First, let's express the number of pieces of mail in scientific notation. The given number is 1.52 × 10¹⁰.
Next, we multiply this number by the cost of a single stamp, which is $0.55.
Multiplying these two values gives us:
1.52 × 10¹⁰ * $0.55 = $8.36 × 10⁹.
Therefore, the total cost to deliver all the pieces is $8.36 × 10⁹, expressed in scientific notation to the exact decimal place.
