Question

For the spring picnic, Mr. Jones served 85 hot dogs to 50 people. Mr. Jones expects 68 people at the fall picnic. Which proportion could be used to find how many hot dogs Mr. Jones needs for the fall picnic?

Answer 1

If Mr. Jones served 85 hot dogs to 50 people the proportion of hot dogs is:

$\frac{85}{50}\text{ hot dogs/person}$

If he expects 68 people at the fall picnic, the amount of hot dogs he will need is the number of people multiplied by this proportion:

$\text{hot dogs = 68p }\cdot\frac{85}{50}\text{ hot dogs/p}$

Answer

The proportion that could be used to find how many hot dogs Mr. Jones will need for the fall picnic is 85/50

He will need 115.6 hot dogs (since the number of hot dogs is a whole number, He will have to buy 116 hot dogs)
