Janna is playing an online trivia game. she has 50 points and earns 2 points for each correct answer. she will advance to the next round if her score is over 68 points.

Answer 1

To determine how many correct answers Janna needs to provide in order to advance to the next round, we need to find out how many additional points she needs to exceed a total of 68 points.

Currently, Janna has 50 points and needs to have more than 68 points, so:

\[ 68 - 50 = 18 \]

This means she needs to earn at least 19 more points (since "over 68" means she needs at least 69 points).

Since she earns 2 points for each correct answer, we can calculate how many correct answers she needs to achieve the required points:

\[ \text{Number of correct answers} = \frac{\text{Points needed}}{\text{Points per correct answer}} = \frac{19}{2} = 9.5 \]

Since she can't answer a half question, she needs to round up to the next whole number. Thus, Janna needs to answer:

\[ 10 \text{ correct answers} \]

This will give her:

\[ 50 + (10 \times 2) = 50 + 20 = 70 \text{ points} \]

So, Janna needs to answer 10 correct answers to advance to the next round.
