Find the percent of discount (change) if an item that was priced at 54.00 is now on sale for 45.95

  about 14.9%

Step-by-step explanation:

Percent change can be computed using the formula ...

  percent change = ((new value)/(old value) -1) × 100%

For the given numbers, this is ...

  percent change = (45.95/54.00 -1) × 100% ≈ -14.907%

The discount is about 14.9%.

Computed this way, the sign of the percentage change is negative for a decrease (discount), and positive for an increase.
