Question

As of april 1,2010 there were 53,364 certains in the United States . In the year 2060,that number is projected to increase to 601,000.what is the projected percent increase to the nearest hundredths place?

Answer 1

601000-53364=547636, so the percentage increase is 100(547636/53364)=1,026.23%.

Alternatively: 601000/53364=100(11.2623-1)%=100×10.2623%=1,026.23%.

If the increase was to 60100, then the percentage increase would have been 12.62%:

60100-53364=6736⇒100(6736/53364)=12.62%; or:

60100/53364=100(1.1262-1)=100×0.1262=12.62%.
