Paint the Walls
The height of the bedroom is 9 feet. There are 4 rectangular windows in the room that are
each 30 inches wide and 36 inches high. You will not paint the windows, the floor, or the
ceiling. You will paint the rest of the room, including the door. Your client likes two colors,
Light-at-Dawn and Cloudy Sunrise. Both colors are only available in 1-gallon cans. Light-at-
Dawn: The regular price of a 1-gallon can is $24, but it is on sale for 25% off the regular price.
This type of paint requires 2 coats. Cloudy Sunrise: The price of a 1-gallon can is $28. This type
of paint only requires 1 coat. Each gallon of paint will cover an area of about 350 square feet.
Your client has stated that if the cost for using Cloudy Sunrise is no more than 5% greater
than the cost for using Light-at-Dawn, then you should use Cloudy Sunrise. Which paint color
should you use? Explain or show your reasoning. You may use diagrams, drawings, or
equations as well as words.
