Answer: D. 25

The answer is D. 25.
Here is the step-by-step solution in plain text:
Subtract 22.26 from 72.26 to find what the number equals after being multiplied by 2:
72.26 - 22.26 = 50
Divide 50 by 2 to find the original number:
50 / 2 = 25
Check: 25 multiplied by 2 is 50, and 50 plus 22.26 equals 72.26.
