Answer:
Shaun make her first error in step 3. Answer C
Step-by-step explanation:
If have the same units you can simply add them, Like this:
Step (1)
18.5w+6.5w-2.8w= 149.10 <em>(everything in the left side is in terms of w)</em>
Step(2)
25w-2.8w= 149.1 <em>(add 18.5+6.5)</em>
Step(3)
<u><em>Here you have to add the terms of w</em></u>
(25-2.8)w=149.1
22.2w=149.1
Step(4)
Here you clear w
w=149.1/22.2
w=6.72
