$5.$ Thad Morgan, a motorcycle enthusiast, has been exploring the possibility of relaunching the Western Hombre brand of cycle that was popular in the $1930$s$.$ The retro$-$look cycle would be sold for $$10,000,$ and at that price, Thad estimates he could sell $600$ units each year. The variable cost to produce and sell the cycles would be $$7,500$ per unit. The annual fixed cost would be $$1,125,000.$

a$.$ What is the break$-$even in unit sales?

Break$-$even in unit sales

b$.$ What is the margin of safety in dollars?

Margin of safety in dollars

c$.$ What is the degree of operating leverage?

Note: Round your answer to $2$ decimal places.

d$.$ Thad is worried about the selling price. Rumors are circulating that other retro brands of cycles may be revived. If so$,$ the selling price for the Western Hombre would have to be reduced to $$8,000$ to compete effectively. In that event, Thad also would reduce fixed expenses to $$889,000$ by reducing advertising expenses, but he still hopes to sell $600$ units per year.

What would the net operating income be in this situation?

Note: Negative amount should be indicated by a minus sign.
