Question 164259: A recent college graduate has job offers for a sales position in two computer firms. Job "A" pays 25,000 per year plus 5% commission. Job "B" pays only 20,000 per year, but the commission rate is 10%. How much yearly business must the salesman do for the second job to be more lucrative?

You can put this solution on YOUR website! <.pre>
Let  =sales
We equate the 2 Jobs' rate: 
 ------> At this sales you can choose either Job (A or B) because the salary will just be the same. Sales higher than this, Job B will be lucrative (better)
Let's see, x=$101,000
Job A @ 5%:
 =$30,050
Job B @10%:
 =$30,100
See, the higher the sales on $100,000 more money you're getting on Job B.
Try $125,000? $150,000?
Thank you,
Jojo
