Answer :
Answer:
1) 62.5%
2) 8-x/8=y/100 (where y is the percent)
Step-by-step explanation:
1) so there’s 8 questions in total cause each question si 5 points and 40 points is the max so 40/5=8
write a proportion where 8-3/8=y/100 (it’s 8-3 because it’s total question minus the wrong questions and you’ll get the remaining points and put it over a hundred since the max score you can get is a hundred.
so 5/8= y/100
cross multiply
500=8y
Divide 8 on both sides
you’ll get 62.5
2) Jist use the equation 8-x/8=y/100
( where x is the wrong amount of questions and y is the total percent)
Answer:
1st Question the answer is 25/40
2nd Question the answer is 40-(x*5)=answer
Step-by-step explanation:
1st Answer: Multiply 3 questions by 5 points and subtract that answer from 40 and that gives us the final answer -25-
