$251

Step-by-step explanation:

Let x be the number of ounces for the additional cost, we can write an expression to determine the cost of 10-ounce envelope. The first ounce is $54 therefore the remaining 9 ounces wiht cost $22.

$53+22\cdot{x}=53+22\cdot{9}=53+198=251$

The cost of mailing 10 ounces envelope is $251

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
