Answer:
<u>1. Emily scored 60 points in the first round</u>
<u>2. Emily scored minus 30 points in the second round</u>
<u>3. Emily's final score is 15 points.</u>
Step-by-step explanation:
1. Let's review all the information given to us to answer the questions correctly:
Points awarded for a correct answer = 20
Points deducted for a incorrect answer = 10
2. Let's calculate the score of Emily in the first round:
Score = 7 * 20 - 8 * 10
Score = 140 - 80
Score = 60
<u>Emily scored 60 points in the first round</u>
<u>3. </u>Let's calculate the score of Emily in the second round:
Score = 4 * 20 - 11 * 10
Score = 80 - 110
Score = - 30
<u>Emily scored minus 30 points in the second round</u>
<u>4. </u>Let's calculate the final score of Emily:
Final score = (Score 1st round + Score 2nd round)/2
Final score = (60 + - 30)/2
Final score = (60 - 30)/2 = 30/2 = 15
<u>Emily's final score is 15 points.</u>
