a.
To find: The quantity of paints which should buy.
a.

Answer to Problem 22PTTS
The paint should buy
Explanation of Solution
Given information: You are painting a room that is
The paint you choose is available in both
Calculation: The total area of the vroom is
The area of the doors is
The area of the windows is
Therefore, The area of the wall is to be paint,
Since, You plan to put
Than, The area of paint should be doubled i.e.
Therefore, paint should buy,
Hence, The paint should buy
b.
To find: How much will it coast to put
b.

Answer to Problem 22PTTS
The coast to put
Explanation of Solution
Given information: You are painting a room that is
The paint you choose is available in both
A
You have budgeted
Calculation: The total area of the vroom is
The area of the doors is
The area of the windows is
Therefore, The area of the wall and window is to be paint,
Since, You plan to put
Therefore, paint should buy,
And
The costs of
And the coasts of
Therefore, The total coast of
Hence, I can afford to paint the inside walls of the closet, excluding the door with
