Show me the steps to solve

$1.$ David Tan, sales director, of Pub$$s Toy Ltd$,$ negotiated with a new customer on the volume and selling price of its popular product $$ Monster Craz. David has been informed of the costs of manufacturing the product $$ variable production cost $$15$ each and fixed production overhead $$4,000,000$ for the expected volume between $40,000$ units and $80,000$ units. Selling and administrative variable and fixed expenses are $$3$ per unit and $$40,000$ for the same expected volume range. David expected to sell $50,000$ units of Monster Craz. How much is the minimum price for the deal, if a minimum targeted profit of $$500,000$ is expected?

$2.$ Boring is the one of the largest commercial airplane manufacturers. In $2007,$ it began development of the $7$V$7-$III, a $240-$passenger plane with a range up to $4010$ miles. First deliveries will take place in $2010.$ The price will be about US$$70$ million per plane.

Assume the annual fixed costs for the $7$V$7-$III are US$$950$ million and its variable cost per $7$V$7-$III is US$$45$ million.

Required:

a$)$ How many planes does Boring need to sell in order to break$-$even?

b$)$ If Boring managed to clinch contracts for $42$ planes in $2010,$ then what would be its projected operating profit?

If Boring automated its production process further and increased its fixed costs by US$$84$ million then it can achieve a reduction of variable cost per airplane by US$$2$ million.

c$)$ What are the break$-$even point?

d$)$ the operating profit if $42$ planes will be sold in $2010?$

e$)$ Your comments on the results?

Ignore question $($c$)$ to $($e$)$ above. If fixed costs do not change but variable costs increase by $10\%$ before deliveries of any airplanes in $2010.$

f$)$ What is the new break$-$even point?

g$)$ What strategies might Boring use to help assure profitable operations in light of increases in variable costs?
