The company paid $2000 for the printer
Step-by-step explanation:
Let x be the price of the printer for which the company bought it.
If x is the price of printer, then 25% of x will be the profit made by the company.
That is:
0.25x
According to the statement,
The cost and profit earned by company are equal to 2500
So,
Dividing both sides by 1.25
Hence,
The company paid $2000 for the printer

She will also need the minimum value, the median, the upper quartile and the lower quartile.
The box will be drawn from the upper quartile to the lower quartile, with a vertical line at the median. The whiskers will go from the box to the highest and lowest values.

Step-by-step explanation:
It’s a simple one to write. There are many trios of integers (x,y,z) that satisfy x²+y²=z². These are known as the Pythagorean Triples, like (3,4,5) and (5,12,13). Now, do any trios (x,y,z) satisfy x³+y³=z³? The answer is no, and that’s Fermat’s Last Theorem.
On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42?
That turned out to be much harder—as in, no one was able to solve for those integers for 65 years until a supercomputer finally came up with the solution to 42. (For the record: x = -80538738812075974, y = 80435758145817515, and z = 12602123297335631. Obviously.)
