Assessment Task Weighting Mark
Written Assignments 30% 40
50
Participation 30% 12

Exam 40% ?
100
The combined assessment marks that needs to be obtained by Kermit in order to get the
Credit (60% - 69%) score is calculated as shown below.
Let the exam mark obtained by Kermit is x.

Written assignments score = 30% of 40 = 40*30% = 12
Participation score = 30% of 12 = 12*30% = 3.6
Exam score = 40% of x = x*40% = 0.40x
The minimum percentage for Credit score = 60%
Total marks = 60% of {(30%* 50) + (30%*20) + (40%*100)} = 60% * 61 = 36.6
Hence,
Minimum marks for Credit score = 12 +3.6 +0.40x = 36.6
15.6+0.40 x=36.6
x=52.5
And
The maximum percentage for Credit score = 69%
Total marks = 69% of {(30%* 50) + (30%*20) + (40%*100)} = 69% * 61 = 42.09
Maximum marks for Credit score = 12 +3.6 +0.40x = 42.09
15.6+0.40 x=42.09
x=66.23
Therefore, it can be concluded that assessment marks that needs to be obtained by Kermit in
order to get the Credit (60% - 69%) score would fall between 53 and 67.
Question 8
(i) Three less than the product of eight and a number x
Here,
The first number = 8
The second number = x
Product of eight and a number x = 8x
The product is less than 3 = 8x – 3
