Answer
# Explanation:
## Step1: Calculate additional ounces
The envelope is 10 - ounce. The first - ounce is charged differently. So the number of additional ounces is $10 - 1=9$.
## Step2: Calculate cost of additional ounces
Each additional ounce costs $0.22$. So the cost of 9 additional ounces is $0.22\times9 = 1.98$.
## Step3: Calculate total cost
The first - ounce costs $0.54$. Add the cost of the first ounce to the cost of the additional ounces. The total cost is $0.54+1.98 = 2.52$.
# Answer:
D. $2.52$
