Answer 1

Hello Mal,

To determine the percent increase in a problem such as the one above, you do the following:

Subtract the highest number from the lowest, or in other words, determine the increase between the two numbers.

Second, divide the increase by the original number; in this case 19000.

Third, multiply that number by 100 to determine the percentage of increase. If you have a negative number you have a percentage of decrease. So,

Step One

25270

19000

---------

6270

Step Two

6270/19000 = .33

Step Three

.33

100

------

33%

Therefore, your answer is C.

I hope this helps and that you have a great week. Please feel free to provide any feedback, ask further questions about this solution, or reach out to me should you need to. Best!
