Question

You are hosting a party. You are providing 3 food items. Each guest brings 2 food items. Write an equation in two variables that represents the total number of food items.

Answer 1

Answer:

y = 3 + 2x

Step-by-step explanation:

Let y = Total number of food items

Let x = Number of guests

y = 3 + 2x

Example:

If there are 14 guests, we have:

y = 3 + 2(14)

y = 3 + 28

y = 31

So the equation gives us a total number of 31 food items from both you and the guests.
