A TV is marked up from $200 to $300.
Determine from the wording of the problem, which value is v1 and which is v2. Compute percent change, rounding decimal answers to two places. Express your result in a sentence stating how much the second value is less or greater than the first value. For example: "This year's sales are 50 percent less than last year's sales."
The $300 price represents a 50% markup of the $200 price.
Note: When you reverse v1 and v2 you get a different percentage change.
