Hello!
To find the cost of 12 oz:
first oz = $0.37
Every oz after = $0.23
12 - 1 = 11
First oz = $0.37
11 × .23 = 2.53
2.53 + 0.37 = 2.9
A 12 oz package in first class would cost $2.90.
Hope I helped you! :)
PS. Next time please add the answer choices! :)

The length of rectangle is 37.5 and width is 12.5
Step-by-step explanation:

Width of rectangle = w
Length of rectangle = 3w
Perimeter of rectangle = 100
Perimeter = 2(Length+Width)
Dividing both sides by 8
Width of rectangle = 12.5
Length of rectangle = 3(12.5) = 37.5
The length of rectangle is 37.5 and width is 12.5
