Answer:
Problems left to complete = 9
Step-by-step explanation:
Given that:
Number of problems on the test = 45
Percent of completed problems = 80%
Number of completed problems = 
Number of completed problems = 0.8 * 45 = 36
Problems left to complete = 45 - 36
Problems left = 9
Hence,
Problems left to complete = 9
