Solve Problem $9\mathrm{.}6$ from the book. HOWEVER, assume a $3-$ cy bucket instead of $\frac{31}{2}-$ cy bucket; and a cost per hour of $$150\mathrm{.}00$ instead of

$$130\mathrm{.}00.$ Make sure to show all $6$ steps for each condition:

A crawler hoe having a $3-$cy bucket and whose cost per hour, including the wages to an operator, is $$150,$ will excavate and load trucks under each of

the stated conditions. The maximum digging height of the machine is $26ft.$ Determine the cost per cubic yard for each condition.
