Jackie surveyed 50 students at her school and found that 0.64 of the students she surveyed said their favorite class is math. Another 24% of the students she surveyed reported that their favorite class is science. How many more studenw in the survey prefer math over science? (1 point)
First, we need to find the number of students who prefer math out of the 50 surveyed by multiplying 0.64 * 50 = <<0.64*50=32>>32.
Next, we need to find how many of the students surveyed prefer science. To do this, we multiply 0.24 * 50 = <<0.24*50=12>>12.
To find how many more students prefer math over science, we subtract the number of students who prefer science from the number of students who prefer math by performing the operation 32 - 12 = <<32-12=20>>20. Answer: \boxed{20}.
