The population of north dakota was about 672,000 in 2010. the population is projected to be about 630,000 in 2020. find the percent decrease of the population of north dakota round to the nearest tenth of a percent.

6.25% decreased

Step-by-step explanation:

630,000/672,000= 0.9375

so in 2020 its 93.75% of what the 2010 population was.

So its 100-93.75= 6.25% decreased

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
