Answer:
80 %
Step-by-step explanation:
A college has a 30% completion rate, meaning that 30% of all students who start at the college complete their studies.
If the president of the college sets a goal of increasing this number by 50%.
Therefore, the new completion rate goal will be (30 + 50) = 80%. (Answer)
There may arise a confusion between the words "increasing by 50%" and "increasing to 50%".
If it was said to set a goal of increasing this number to 50%, then the new completion rate goal would have been exactly 50%.
