what you do is multiply .65 by 80 which gives you 52 students. Then you make 15% into a decimal( .15) and also multiply it by 80 which gives you 12 students.Finally you subract 12 from 52 which is 40. The answer is 40 students.

Answer:

40 more students in the survey prefer math over science.

Step-by-step explanation:

Kim surveyed 80 students at her school and found that 0.65 of the students she surveyed said their favorite class is math.

This becomes 0.65\times80=52 students said their favorite class is math.

Another 15% of the students she surveyed reported that their favorite class is science.

Means \(0.15\times80=12\) students said that their favorite class is science.

Now to know how many more students in the survey prefer math over science we can do :

\(52-12=40\)

Therefore, 40 more students in the survey prefer math over science.
