Answer:
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.
