Answer: See explanation

Step-by-step explanation:

Here's the complete question:

Kevin correctly answered 75% of his 32 test questions. how many questions would kevin have to answer to get more that 80% correct?

The number of questions he answered correctly will be:

= 75% × 32

= 75/100 × 32

= 3/4 × 32

= 24

He got 24 questions correctly.

To get more than 80% correctly, he will have to answer:

= 80% × 32

= 80/100 × 32

= 4/5 × 32

= 128/5

= 25.6 = 26

He will have to answer at least 26.
