Answer:
The total number of ways are 315.
Step-by-step explanation:
Consider the provided information.
A certain university will select 1 of 7 candidates eligible to fill a position in the mathematics department.
Therefore the number of ways are:
ways
There are 7 ways to fill math position.
2 of 10 candidates eligible to fill 2 identical positions in the computer science department.
Therefore the total number of ways are:

Hence, there are 45 ways to fill computer science position.
Total number of ways = 7 × 45 = 315 ways.
Hence, the total number of ways are 315.
39/50= 0.78 times 100= 78
78 is Donovan's score
if maci's score is 10 percentage points higher
78+10=88
x /50 =0.88 times 100= 88
x=44
each question is 2 points: 88-78= 10/2=5
Maci answered 5 questions correctly.
