Frida Ramirez · Answer 1

80 x. 55 = 44 people whose favorite class is math

80 x. 15 = 12 people whose favorite class is science

(15 as a decimal is written as. 15)

44 - 12 = 32 more students prefer math over science

Max Duffy · Answer 2

80 (.55) = 44 students prefer math

80 (.15) = 12 students prefer science

44-12 = 32 more students prefer math than science
