Lucy surveyed 80 students at her school and found that 0.65 of the students she surveyed said their favorite class is English. Another 15% of the students she surveyed reported that their favorite class is Art. How many more students in the survey prefer English over Art?

$${\mathtt{80}}{\mathtt{\,\times\,}}{\mathtt{0.65}} = {\mathtt{52}}$$

 

$${\mathtt{80}}{\mathtt{\,\times\,}}{\mathtt{0.15}} = {\mathtt{12}}$$

 

52-12=40
