Sales price $ $431\mathrm{.}00$ per unit

Variable costs $191\mathrm{.}00$ per unit

Fixed costs $631,000$ per year

Assume that the projected number of units sold for the year is $3,800.$ Consider requirements $($b$),($c$),$ and $($d$)$ independently of each other.

Required:

A$.$What will the operating profit be$?$

B$.$What is the impact on operating profit if the sales price decreases by $20$ percent? Increases by $10$ percent?

C$.$What is the impact on operating profit if variable costs per unit decrease by $10$ percent? Increase by $20$ percent?

D$.$Suppose that fixed costs for the year are $20$ percent lower than projected, and variable costs per unit are $10$ percent higher than projected. What impact will these cost changes have on operating profit for the year? Will profit go up$?$ Down? By how much?

Please do all part a$-$d will rate!
