Mr. Newman hired painters to paint two storage
containers similar to the one shown. If each can of
paint costs $15 and will cover 188 square feet, how
much will it cost to paint both containers?
O $108
9 ft
$120
8 ft
$230
$240

A. PAINTING (function calculatePaintCost) This contractor charges $300 to paint each room with two coats of paint. The webpage asks the user to enter the number of rooms to be painted in a textbox. The user has an option to have a third coat of paint. If the user clicks the YES radio button, the cost of painting is increased by 30%. [Example: assuming the third coat of paint is wanted, it will cost $1950 to paint 5 rooms.] The function returns the cost of painting.

B. HEATING DUCT WORK (function calculateDuctCost) Two heating vents need to be installed in opposite diagonal corners of the room. To connect these two vents, ductwork has to be placed in the wall along the length of the room, and then within the adjacent wall along the width of the room. [So, if the room is 15 feet, by 10 feet, there is 25 feet of ductwork in all.] The cost of this job will be $400 plus the cost of the ductwork. Ductwork costs $10 for each foot. And now the interesting part, the contractor is offering to save the user money (“cutting corners”) by installing the ductwork diagonally across the ceiling, which will of course be less of a distance. Given this is considered a somewhat shoddy practice, the contractor will ask the owner if they are interested in this option. The law only allows them to do this if the diagonal distance is less than 20 feet. Your function must calculate the cost of this job using the diagonal only if the owner is ok with it and it meets the requirement of the law and the distance is short enough; otherwise it should calculate the cost in the normal way going along the length and width walls. Hint: you need to use an IF-THEN-ELSE for this and your condition needs to use a Boolean (logical) operator. You need to calculate the size of the diagonal from the info they supply. You may remember that if a rectangular room has a length L and a width W, its diagonal = Math.sqrt(L*L + W*W) [Example, if a room is 9 X 12, then its diagonal is 15. This distance is small enough to allow the cutting corners approach, so if the owner is ok with doing it, the ductwork job will cost $550 which is 400+10*15.] The function returns the cost of duct work.
