If the original quantity is 14 and the new quantity is 24, estimate the percent change

Answer 1

14 is about twice 24. 100% of 14 is 14. 200% of 14 is 2x14=28. 24 is approximately 200% of 14.

To calculate, you want part/whole and then multiply out of 100 (percent is the proportion when whole is 100). Your part is 24, and your whole is 14. 14/24 =1.71, so 24 is 174% of 14.
