If Cabinetmaker $1$ has additional hours available, would the optimal solution change? If required, round your answers to three decimal places. If your answer is zero, enter $"0".$ Explain.

No

because Cabinetmaker $1$ has

slack

$120$

hours. Alternatively, the dual value is fill in the blank $34$

which means that adding one hour to this constraint will decrease total cost by $fill in the blank $35$

$.$

If Cabinetmaker $2$ has additional hours available, would the optimal solution change? If required, round your answers to three decimal places. If your answer is zero, enter $"0".$ Use a minus sign to indicate the negative figure. Explain.

Yes

because Cabinetmaker $2$ has a

$25$

$.$ Therefore, each additional hour of time for cabinetmaker $2$ will reduce cost by a total of $ fill in the blank $39$

$4\mathrm{.}7267$

per hour, up to an overall maximum of fill in the blank $40$

total hours.

Suppose Cabinetmaker $2$ reduced its cost to $$39$ per hour. What effect would this change have on the optimal solution? If required, round your answers to three decimal places. If your answer is zero, enter $"0".$

What is the total cost of completing both projects? If required, round your answer to the nearest dollar.

Total Cost $=$ $ fill in the blank $47$
