Please explain

machine are as follows:

$($a$)$ For each component, calculate the profit margin $($profit margin $=$ selling price $-$ material cost $-$ labor cost$).$

Component $1$: $

Component $2$: $

Component $3$: $

Formulate and solve the model to determine the maximum profit. If the constant is $"1",$ it must be entered in the box. If an amount is zero, enter $"0".$

Let C$\_(1)=$ units of component $1$ manufactured

C$\_(2)=$ units of component $2$ manufactured

C$\_(3)=$ units of component $3$ manufactured

$($d$)$ If more time could be made available on the grinder, how much would it be worth? Explain.

$,$ because the constraint related to the time available on the grinder

binding.

$($e$)$ If more units of component $3$ can be sold by reducing the sales price by $$4,$ should the company reduce the price?

Select your answer $-$

$,$ because the production of component $3$ would be

profitable than the production of the other two components and at the reduced price

Select your answer $-$

of component $3$ would be produced.
