Answer:
404%
Step-by-step explanation:
To find the percentage difference do the following: (FV - SV)/|SV| * 100
(1260 - 250)/|250| * 100 <em>{Subtract 250 from 1260 to get 1010. The absolute value of 250 is 250.}</em>
1010/250 * 100 <em>{Divide 1010 by 250 to get 4.04, or 101/25.}</em>
101/25 * 100/1 <em>{CROSS CANCELLATION}</em>
101 * 4 <em>{Multiply 4 by 101 to get 404.}</em>
