9.50 + (2.20)r
For example if he fixed 3 watches
9.50 + (2.20)3
We plug in 3 for r and he makes 6.60 extra.
This is = 4 therefore no property is applied
S + 4t = r
subtract 4t from both sides
s = r - 4t answer

Answer: addition property of inequality</h3>
================================================
Explanation:
These are the steps to focus on
step 3: -6x - 8 < -2
step 4: -6x < 6
The move from the third step to the fourth step has us adding 8 to both sides. Therefore, we use the addition property of inequality.
That property has four forms
- If
then 
- If
then 
- If
then 
- If
then 
It's similar to the idea of starting with a = b, then adding c to both sides to get a+c = b+c
We add the same thing to both sides to keep things balanced.
I think the answer is 50 dollars more the amount
