Answer: b) 625 - 25 |x - 1990| = 550

Step-by-step explanation:

According to the question,

The annual profit of a company was determined by subtracting from $625,000 the product of $25,000 and the number of years either before or after 1990.

That is, On x year the total profit is,

P(x) = 625,000 - 25,000 |x - 1990|

But again according to the question,

On x years the profit is $ 550,000

Thus, 625,000 - 25,000 |x - 1990| = 550,000

⇒ 625 - 25 |x - 1990| = 550 ( by dividing both sides by 1000)

Therefore, Option b) is correct.

Surface area is the sum of the areas of each side of a three dimensional object.

There are two sides that are 11x9, two sides that are 9x3, and two sides that are 11x3.

So the surface area is:

2(11)(8)+2(9)(3)+2(11)(3) = 296 ft^2
