Given:
Total number of questions = 50
Number of correct answers = 35
Number of wrong answers = Total number of questions - correct answers
= 50 - 35 = 15
Therefore, the number of questions she did not answer correctly = 15
To find the percentage Janet did not answer correctly, use the formula:
[tex]\text{ \%of wrong answers=}\frac{wrong\text{ answers}}{\text{Total number of questions}}\times\frac{100}{1}[/tex]Thus we have:
[tex]\text{ \% of wrong answers = }\frac{15}{50}\times\frac{100}{1}=0.3\times100=30\text{ \%}[/tex]Therefore, the percent of questions Janet did not answer correctly is 30 percent.
ANSWER:
30%
