Answer:

$840

Step-by-step explanation:

This is an example of a compound percentage change.

To work this out you should multiply $2450 by 0.70 to the power of 3.

You would multiply by 0.70 as you are decreasing the amount by 30%. And so by multiplying the amount by 0.70 you are decreasing it by 30% and by doing it to the power of 3 you are decreasing it 3 times.

2450*0.70^{3} =840.35
