Minimum 350 buns and hot dogs will be needed to feed all the people.
We are given a information that:
For a picnic, you need to feed at least 700 people.
if you want to feed everyone, but still have equal numbers of buns and hot dogs.
Let 'x' be the number of hot dogs and bun each required,
Also according to the above information we have:
⇒ x+x≥ 700
⇒ 2 x≥ 700
i.e. x≥ 350.
Hence we require a minimum number of 350 packages of buns and hot dogs, respectively.
it would be 6xy and -16xy.
