Question

If postage costs $.54 for the first ounce and $.22 for each additional ounce, calculate the cost of mailing a 10-ounce envelope.

Answer 1

Answer:

$2.52

Step-by-step explanation:

Mass of envelope = 10 ounce

Now, it has been given that postage costs $.54 for the first ounce and $.22 for each additional ounce.

Therefore, the cost of first ounce =$ 0.54

Now, we are left with 9 more ounces. hence cost of 9 ounces should be 9×0.22 = $1.98

Therefore, total cost of mailing a 0- ounce envelope is

0.54 + 1.98

= $2.52

Answer 2

First = $ 54 Another postage = $ 22 So the cost is = ($ 54 x 1) + ($ 22 x 9) Cost = $ 54 + $ 198 = $ 252 #brainly.co.id/profil/FadhilPrawira-230178
