Lucy has 20 questions in her science home work
Solution:
Given that,
Lucy correctly answered 70% of the questions on her science homework
She counted 14 correct answers on her paper
To find: Number of questions in her science home work
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
[tex]70 \% \times x = 14\\\\\frac{70}{100} \times x = 14\\\\0.70x = 14\\\\x = \frac{14}{0.70}\\\\x = 20[/tex]
Thus Lucy has 20 questions in her science home work
