Answer:
B. 8
Step-by-step explanation:
Calculate how many 2 point answers and 5 point answers there are.
2 x 8 = 16
Since there are half as many 5 point answers as there are 2 point answers,
5 x 4 = 20
calculate how many remaining questions there are. The numbers would be 8 since you had 8 2 point questions and 4 since half of 8 is four.
8 + 4 = 12
Subtract that number by the total questions, which is 28.
28 - 12 = 16
Next figure out how many 4 point questions you had (28-12=16)
16 x 4 = 64
To check your work add up the totals and see if they match up to 100.
16 + 20 + 64 = 100
