Vikki is about to take the final exam
in her history class. prior to the test,
vikki's teacher told her that her grade
in the course was an 87.5 percent
and that she needed to score a 196
out of 200 on the final exam to raise
her course grade to 90 percent. each
student's course grade is determined
by dividing the total number of points
he or she earned throughout the
semester by the total number of
possible points. how many points had
vikki earned in the class prior to the
final exam?
