a.
To write inequality equation.
a.
Answer to Problem 5.1.2.13P
Inequality
100- x <27
Explanation of Solution
Given information:
Calculation:
Let x be the number of marks obtained by M
Total marks=100
M loses less than 27
Then, inequality
100- x <27
Subtracting 100 both sides of inequality
100- x -100<27-100
On solving,
- x <-73
Multiplying by -1 both sides of inequality
x>73
Hence, M will obtain more than 73 marks.
b.
To explain about M's grades.
b.
Answer to Problem 5.1.2.13P
M will obtain more than 73 marks.
If M obtained marks between 74 to 82 marks
Then, grade is C.
If M obtained marks between 83 to 91 marks
Then, grade is B.
If M obtained marks between 92 to 100 marks
Then, grade is A.
