Answer:
$12.65
Step-by-step explanation:
Given that the wall is 23 feet long and 8 feet high.
As the wall is rectangular, so the area of the wall,
A=23x8=184 square feet.
As a gallon of paint costs $11 and covers 320 square feet of area, so
Cost of paint for 1 square foot area = $ 11/320 per square foot.
Cost for 1 coat of paint = $ (11/320)x184
Cost for 2 coat of paint = $ (11/320)x184x2= $ 12.65
Hence, cost requires for 2 coats of paint is $ 12.65.
<span>Let x = price increase ( in dollars )
Then the revenue is (6+x) * (3000 - 1000x) and the cost is (3000 - 1000x).
thus the profit P = revenue minus cost = 18,000 - 6000x^2 - 3000 + 1000x = 15,000 + 1,000 - 6,000x^2
take the derivative and set it equal to zero and I think the price increase x should be 1/12 so the final price would be original price plus price increase or 6 + 1/12</span>
