In part c, you determined that the proper ratio of packages of buns, packages of patties, and jars of pickles is 3: 2: 4. if you want to feed at least 540 people, but also maintain the proper ratio, what minimum number of packages of buns, packages of patties, and jars of pickles do you need, respectively?

 First let us determine how many we need for 540 people (assuming the ratio is per person) 

540 x (3:2:4) 

buns : patties : pickles 
1620 : 1080 : 2160 

Divide each one by the pakage size 

packets of buns : packets of patties : jars of pickles 
1620 / 8 : 1080 / 12 : 2160 / 18 

= 202.5 : 90 : 120

Round the non-whole number up since we cannot have a fractional bun: 

packets of buns : packets of patties : jars of pickles 
203 : 90 : 120

The answer would be B)

Hope this helped
