Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
Answer:y=2x+13
Step-by-step explanation:You would distribute the 2 to get y-3=2x+10. Then add the three over to get your final answer.
I = Prt
6300 = P * .07 * (60/12)
6300 = .35P
6300 / .35 = P
18000 = P
$18,000 is the answer you are looking for! I hope this helps! :D
