Answer: RS 49.8
Step-by-step explanation:
Given the following :
Fixed cost = RS 4430
Break even point = 89 units
Recall:
Break even point in units = Fixed cost ÷ contribution margin
Therefore,
Contribution margin equals;
(Fixed cost ÷ break even point in units)
= 4430 / 89
= 49.775280
= RS 49.8
In the attached diagram you can see the graph of the function 
As you can see graph is:
1. increasing from x = −2 to x = −1
2. decreasing from x = 0 to x = 1
3. decreasing and then increasing from x=1 to x=2
4. increasing from x=2 to x=4.
Answer: correct choice is B.
Answer:
The least score the student can get is 71 to get an overall B average at the end of the year.
Step-by-step explanation:
Let the score she needs to get be = x
We now have to take the mean of all the five subjects <em>(including x)</em> and equate it to the least score she can have to get a B grade.
Let us take the least score the student needs to get a B grade to be 85
Mean of all 5 scores =




The least score the student can get is 71 to get an overall B average at the end of the year.
