You and some friends have $30. You want to order large pizzas that are $9 each and drinks that cost $1 each. Define variables and write an inequality that shows how many pizzas and drinks you can order?

Respuesta :

Answer:

The inequality which represents number of pizza and drinks which can be ordered is  [tex]9x+y\leq 30[/tex].

Step-by-step explanation:

Given:

Cost of Pizza's = $9

Cost of drink = $1

Total Money = $30

Let the number of Pizza be x

Also let the number of drinks be y

Since pizza and drink has to be bought within the money they have.

Hence The sum of Cost of pizza multiplied with number of pizza and Cost of drink multiplied with number of drinks should be less than or equal to Total Money.

Framing in equation form we get;

[tex]9x+y\leq 30[/tex]

Hence The inequality which represents number of pizza and drinks which can be ordered is  [tex]9x+y\leq 30[/tex].
