Unfortunately you have found how many like brownies NOT how many MORE like brownies than cookies.

70%like brownies,  30% like cookies,  SO  70-40=30% MORE like brownied than Cookies.

30% = 30/100 = 0.30 = 0.3

$${\mathtt{0.3}}{\mathtt{\,\times\,}}{\mathtt{280}} = {\mathtt{84}}$$  students like brownies more than cookies.

$${\mathtt{280}}{\mathtt{\,\times\,}}{\mathtt{0.7}} = {\mathtt{196}}$$

70% of 280 is 196
