Answer: 5.43 square inches
Step-by-step explanation:
Here, the area of triangle ACD = 17.18 square inches,
And, the radius of the triangle having center A = 6 inches
The central angle of the arc CED = 72°
Hence, the area of the sector CAD =
=
=
= square inches
Since, the area of CED = The area of sector CAD - Area of triangle ACD
= 22.608 - 17.18
= 5.428 ≈ 5.43 square inches.

b. For what amount of weekly sales us plan B better than plan A?
Answer:
a)
Expression for plan A:
Total weekly earnings =
Expression for plan B:
Total weekly earnings =
b)
As long as is less than 1000 plan B is profitable.
Step-by-step explanation:
a)
Expression for plan A:
Total weekly earnings =
Expression for plan B:
Total weekly earnings =
b)
For plan B to be better the amount earned by plan B for a specific number of sales should be greater than amount earned by plan A.
Therefore, we can write the following inequality:
Now we can simplify the above inequality to find at which value of it will be profitable to used plan B.
So as long as is less than 1000 plan B is profitable.
Expression A: S= 100+ 100(0.15y) y=Commission
Expression B: S= 150+ 150(0.10y)
Now to get Part B done. Plug in numbers for Y and use the results as the sales continue to increases. For example, start with 5 sales, then go to 10 then 15, and so on and so fourth. Hope I was able help you understand the question a little bit more! :)
A) always
B) sometimes
C) never
