Answer: 13.04%
Step-by-step explanation:To calculate the percentage increase, you can use the following formula:
Percentage increase = ((New value - Original value) / Original value) * 100
In this case, the original value is 460€, and the new value is 520€.
Percentage increase = ((520 - 460) / 460) * 100
Percentage increase = (60 / 460) * 100
Percentage increase ≈ 13.04%
Therefore, the price increase is approximately 13.04%
