i believe the answer is a 20% increase because 12-10 equals 2. there is a 2 record difference so 2 out of 10 is 1/5 of the whole, but you have to convert the numbers and 1/5 of the whole of 100 is 20. sorry if that didn’t make much sense

Answer:
20%
Step-by-step explanation:
The percentage change in a value is calculated from ...
percent change = ((new value) -(old value))/(old value) × 100%
For your given numbers, this is ...
percent change = (12 -10)/10 × 100% = (2/10)×100% = 20%
