PLS HELP!

Perry surveyed 60 students at her school and found that 0.45 of the students she surveyed said their favorite class is math. Another 35% of the students she surveyed reported that their favorite class is science. How many more students in the survey prefer math over science? 6 7 27 21

Answer 1

The answer is 6. You multiply 60 by the .45 and the 35% (which is .35) the subtract the .35 from the .45 (27-21) you get 6.
