I just need help with 9 and 10 I already did 8

this was number 8

8. The company is considering paying the retail coordinator an incentive commission of $0.10 per pair of earrings. This will be on top of the salespeople's commission and there will be no change in fixed salaries. If this change is made, what will be the new break-even point in unit sales and dollar sales? 9. As an alternative to \#8 above. The company is considering paying the store managers $0.20 commission on each pair of earrings sold. The retail coordinator will not get the $0.10 but the salespeople will still get the same commission. If this change is made, what will be the net operating income (loss) if 650,000 are sold? Brent Maldonado 10. Another idea to be tested is that the company will eliminate the 4% sales commission and increase fixed salaries by $250,000. No commissions paid at all, disregard the new commissions from 8 and 9 above. What will be the new break-even point in unit sales and dollar sales. Brent Maldonado
