Hello! I am really having trouble finishing this question; I dont understand the last $3$ parts. Could someone please help me$?$ That would be great! Thank you!

Neptune Company has developed a small inflatable toy that it is anxious to introduce to its customers. The company's Marketing

Department estimates that demand for the new toy will range between $15,000$ units and $30,000$ units per month. The new toy will sell

for $$8\mathrm{.}00$ per unit. Enough capacity exists in the company's plant to produce $20,000$ units of the toy each month. Varlable expenses to

manufacture and sell one unit would be $$4\mathrm{.}00,$ and incremental fixed expenses assoclated with the toy would total $$32,000$ per

month.

Neptune has also identified an outside supplier who could produce the toy for a price of $$3\mathrm{.}00$ per unit plus a fixed fee of $$49,000$ per

month for any production volume up to $20,000$ units. For a production volume between $20,001$ and $45,000$ units the fixed fee would

increase to a total of $$98,000$ per month.

Required:

Calculate the break$-$even point in unit sales assuming that Neptune does not hire the outside supplier. $($Do not round your

intermediate calculations.$)$

How much profit will Neptune earn assuming:

a$.$ It produces and sells $20,000$ units.

b$.$ It does not produce any units and instead outsources the production of $20,000$ units to the outside supplier and then sells those

units to its customers.

Calculate the break$-$even point in unit sales assuming that Neptune plans to use all of its production capacity to produce the first

$20,000$ units that it sells and that it also commits to hiring the outside supplier to produce up to $10,000$ additional units.

Assume that Neptune plans to use all of its production capacity to produce the first $20,000$ units that it sells and that it also commits

to hiring the outside supplier to produce up to $10,000$ additional units.

a$.$ What total unit sales would Neptune need to achieve in order to equal the profit earned in requirement $2a?$

b$.$ What total unit sales would Neptune need to achieve in order to attain a target profit of $$50,500$ per month?

c$.$ How much profit will Neptune earn if it sells $30,000$ units per month?

d$.$ How much profit will Neptune earn if it sells $30,000$ units per month and agrees to pay its marketing manager a bonus of $20$ cents

for each unit sold above the break$-$even point from requirement $3?$

If Neptune outsources all production to the outside supplier, how much profit will the company earn if it sells $30,000$ units?
