Answer:
There are 60 total questions on the course exam.

Given that:
Number of questions finished by Jasmine = 12
Percentage shown on the bar = 20%
The total number of questions will be 100%, therefore, 20% of the questions are equal to 12.

x be the total number of questions on the course exam
20% of x = 12

Dividing both sides by 0.2

Hence,
