Answer:
2m + c = 8
Step-by-step explanation:
Summer's score = Kerry's score + 8
12m + 4c = 10m + 3c + 8
Combining like terms:
2m + c = 8
Answer:
[tex]2m + c = 8[/tex]
Step-by-step explanation:
Let m be the marks scored for each correct multiple choice question.
Let c be the marks awarded for a correct constructed response question.
It is given in the question:
Summer's score = [tex]12m + 4c[/tex]
Kerry's score = [tex]10m + 3c[/tex]
Also, Summer's score - 8 = Kerry's score
or we can write, Summer's score = Kerry's score + 8
Putting in the values, we get:
[tex]12m + 4c = 10m + 3c + 8\\= 12m - 10m +4c - 3c = 8\\= 2m + c = 8[/tex]
The above equation represents that if two multiple questions are correct and a construction based question is correct, then a total of 8 marks is awarded.
Individual values for m and c cannot be calculated because we need two equations to solve for two variable, m and c.
