For your numbers, this is ...
pct change = (250 -200)/200 × 100% = 50/200×100% = 25%
The selling price was 25% more than the cost price.

The width of the box whose height is given as 7 inches and length is three inches more than the width given a volume of 910 is; 10 inches.
<h3>What is the width of the box in discuss whose height, length and width are as described in the task content?</h3>
It follows from the task content that the height of the box is; 7 inches.
Let, x = width of the box and;
x+ 3 = length of the box.
Therefore, since the volume of a box is given by the formula;
V = l × b × h
Therefore, we have;
910 = 7 (x) (x+3)
Divide both sides by; 7
130 = x² + 3x
x² + 3x -130 = 0.
(x+13) (x-10) = 0
Therefore, x = -13 or x = 10.
Ultimately, the possible values of the width are; -13 or 10.
Since the width cannot be a negative number, it follows that the width of the box in discuss is; 10 inches.
