Missing part of the question:
For option A) he will have fixed salary of $600 per week with no commission. What would his weekly sales need to be for him to make more than he would for Option A. (Picture is attached)
Answer:
More than $4,375
Explanation:
If he goes for Option B he will have to earn more than $350 (600-250) as a commission (8% of total sale) along with his salary of $250 to make more than he would for option A i.e. $600.
We have to find the amount whose 8% is $350:
So, if his weekly sale should be more than $4375 to make more than he would have for Option A.
