Answer 2

Problems left to complete = 9

Explanation:

Given that:

Number of problems on the test = 45

Percent of completed problems = 80%

Number of completed problems =
`(80)/(100)*45`

Number of completed problems = 0.8 * 45 = 36

Problems left to complete = 45 - 36

Problems left = 9

Hence,

Problems left to complete = 9
