Question

Find 15 percent of 15 percent of 15 percent of 500 how does this compare to finding 45 percent of 500?

Answer 1

1.) 15% of 15% of 15% of 500
First find 15% of 500 (convert 15% to decimal): 0.15 x 500 = 75
Then find 15% of 75: 0.15 x 75 = 11.25
Then find 15% of 11.25 = 0.15 x 11.25 = 1.6875
1.6875 is our final answer

2.) 45% of 500: 
Convert 45% to a decimal, or 0.45
Then multiply: 0.45 x 500 = 225

Finding 15 percent of 15 percent of 15 percent of 500 is not the same as finding 45 percent of 500 because just adding the percents is not the same thing as we are multiplying 15 percent two more times, not just adding.

Hope this helped! :D

Answer 2

Completely different...

.15*.15*.15*500

500(.15^3)=1.6875

500(.45)=225
