Answer: Revenue is maximum at x=25 and y=0. That is when the firm makes only yellow cakes and no strawberry cakes.
Explanation:
x- Number of Yellow cakes
y- Number of Strawberry cakes
Time constrain is given by



Revenue is given by,

At the vertices, revenue is
At (0,0)
TR = $0
At (0,150)

At (225,0)

Therefore, Revenue is maximum at x=25 and y=0. That is when the firm makes only yellow cakes and no strawberry cakes.
How they spend their time would depend on what is on the estate. If it was a farm, or ranch then they would probably be supervising the agricultural work being done on it or managing the cattle or sheep, say.

The number of subscribers that Tyler loses each month is referred to as churn.
The churn drill is a large drilling machine that bores huge diameter holes in the ground. In mining, they were used to drill into the gentle carbonate rocks of lead and zinc-hosted regions to extract bulk samples of the ore. Churn drills are also referred to as percussion drills as they function by lifting and losing a heavy chisel-like bit which breaks the rock as it falls. Churn drills are handiest in smooth- to medium-density rock of incredibly shallow intensity
Churn drills had been invented as early as 221 BC in Qin dynasty China,[1] capable of accomplishing an intensity of 1500 m. Churn drills in ancient China were built of wood and exertion-intensive but had been able to go through strong rock.

Answer: $22637.98
Explanation:
Based on the information given in the question, the equivalent annual cost of the tool will be calculated as:
We first calculate the present value which will be:
= 10000 + 20000/(1+.10) + 20000/(1+.10)^2 + 20000/(1+.10)^3 + 20000/(1+.10)^4 + 20000/(1+.10)^5
= $85815.74
The the equivalent annual cost will be:
= Present Value/PVIFA(10%,5)
= 85815.74/3.7908
= $22637.98
