Let i_{3} be his monthly income if he accepts this job and s the amount of his monthly sales. In this situation Patrick's income will be $800 plus 10% of s, that is
Let i_{1} be Patrick's income if he accepts the job at the first shop and i_{2} be his income if he accepts the job at the second shop. Find expressions like I did above for i_{1} and i_{2}. Part b asks if i_{1} = i_{2} what is s? Penny
