Lucy has 20 questions in her science home work
<em><u>Solution:</u></em>
Given that,
Lucy correctly answered 70% of the questions on her science homework
She counted 14 correct answers on her paper
<em><u>To find: Number of questions in her science home work</u></em>
Let "x" be the number of questions in her science home work
From given we can say,
Lucy correctly answered 70% of questions
She counted 14 correct answers
70 % of total questions = 14 correct answers
70 % of x = 14

Thus Lucy has 20 questions in her science home work
Answer:
Tallahassee's Range: 6

Step-by-step explanation:
To calculate range, you'd subtract the lowest value from the highest value
Tallahassee:
Highest Value: 90
Lowest Value: 84
Range: 90 - 84 = 6
Key West:
Highest Value: 87
Lowest Value: 83
Range: 87 - 83 = 4
