Answer:

6

Step-by-step explanation:

<h3>Answer: 50%</h3>

Work Shown:

change = new - old = 189-126 = 63

percent increase = (change/old)*100%

percent increase = (63/126)*100%

percent increase = (0.50)*100%

percent increase = 50%

50% of 126 = 0.50*126 = 63

126+63 = 189

The answer is confirmed.
