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
