Final answer:

To find the number of questions on the test, set up a proportion using the percentage of questions Janice answered correctly and solve for x.

Step-by-step explanation:

To find the number of questions on the test, we can set up a proportion using the percentage of questions Janice answered correctly. Let's let x represent the total number of questions on the test.

85% = 17/x

To solve for x, we can cross multiply:

85x = 17 * 100

Dividing both sides of the equation by 85, we get:

x = 17 * 100 / 85

Therefore, Janice answered 85 questions correctly.
