Question

If postage costs are 22 cents for the first ounce and 17 cents for each additional ounce, what is the cost of postage for a letter weighing 3 ounces?

Answer 1

73 cents because you multiply 17 by 3 then you add 22 and get 73

Answer 2

Answer: The cost of postage for a letter weighing 3 ounces= 56 cents.

Explanation:

The cost of postage for the first ounce =22 cents

The cost of postage for each additional ounce = 17 cents

Now, the cost of postage for a letter weighing 3 ounces=
`22\ cents+2(17)\ cents`

Therefore, the cost of postage for a letter weighing 3 ounces=
`22\ cents+34\ cents`

Hence, the cost of postage for a letter weighing 3 ounces= 56 cents.
