Answer:
130%
Explanation:
To find the percentage of increase, we can use the following formula:
% increase = [(new price - old price) / old price] × 100%
In this case, our new price is $276 and our old price is $120.
First, we find the difference between the two prices: $276 - $120 = $156
Then, we divide our answer by the old price: $156 / $120 = 1.3
Lastly, we multiply by 100% to get the percentage of increase: 1.3 × 100% = 130%
Therefore, the percentage of increase is 130%.
