Question

This One Is IMPORTANT Please Help , Ill Medal :)

An architecture firm creates blueprints for office buildings. Last week, they produced four rectangular blueprints for four different projects.

Project A: A 20-inch by 15-inch blueprint with a scale of 1 inch to 4 feet and a projected cost of $22,000.

Project B: A 10-inch by 8-inch blueprint with a scale of 1 inch to 8 feet and a projected cost of $25,000.

Project C: A 15-inch by 12-inch blueprint with a scale of 1 inch to 6 feet and a projected cost of $27,000.

Answer 1

Project D: An 8-inch by 6-inch blueprint with a scale of 1 inch to 12 feet and a projected cost of $30,000.



Order the projects from greatest to least projected cost per square foot of the actual offices.

Answer 2

Okay I'll do project A and the others are the same approach :)

So we have

20in x 15in BUT we know 1 in = 4ft...so lets change these to feet

20 times 4 = 80
15 times 4 = 60

So we have an

80ft x 60ft project here



So if the area is 4800 ft^2 (or 4800 square feet) at a cost of 22000 dollars...that would be

\[\large \frac{22000dollars}{4800ft^2} = 4.5833\frac{dollars}{ft^2}\]
