Question

Your making a dinner for 35 people from a recipe that serves 8 people. The recipe calls for 5 potatoes. How many potatoes will you need for all 35 people? Round up to the nearest integer...

Answer 1

We can solve this problem by proportional relationships:

`\begin{gathered} (8)/(5)=(35)/(x) \\ 8x=5*35 \\ 8x=175 \\ x=(175)/(8)=21.875 \end{gathered}`

Rounding to the nearest integer, you are going to need 22 potatoes for all 35 people.
