So the first thing you have to do is figure out what 16% of 400 is witch is 64 then you have to figure out what 28% of 400 is witch is 112
Ok so now that you have your percentages turned into numbers you have too minus 112 chips by 64 cookies because you need to figure out how many more people chose chips over cookies so your answer would be 48 people chose chips over cookies
Hope this helped you!!
