5. Circuit city : 650 + 0.01(8000) = 650 + 80 = 730 per week
Best Buy : 250 + 0.06(8000) = 250 + 480 = 730 per week
6. Nasir should work at Circuit City. The reason I say this is the salary is 650 no matter what the sales are. And if he has a bad week in sales, he can always count on the salary. Best Buy is riskier because the majority of his pay is more dependent on his sales (which is not guaranteed)......whereas, Circuit City, the majority if his pay is in his salary (and that is guaranteed).
