There are 8 wards on each floor and each ward has the same number of beds. There are a few extra beds on each floor for emergency use. How many extra beds are there on each floor?



Answer :

Let x represent the number of beds per ward.

y represent the number of extra beds

and z represent the number of beds per floor.

In one floor there are 8 wards with x beds on each of them plus a number y of extra beds for emergency.

You can calculate the total number of beds as:

[tex]z=8x+y[/tex]

To determine the number of extra beds per floor, write the expression in terms of y:

[tex]y=z-8x[/tex]
