The weekly soles of a magazine increased from 500,000 to 600,000. By what percent did the magazine sales increase

500,000 * (1 + x) = 600,000

we're going to solve for x

first divide both sides by 500,000

1 + x = 1.2

subtract 1 from both sides

x = 0.2

turn that into a percent by multiplying it by 100

0.2*100 = 20%

the magazine sales increased by 20%

So from 500,000 to 600,000

so assuming 500,000 is 100%

500,000+100,000=600,000

what is 100,000/500,000 in percent

percent means parts out of 100 so

3/100=3% so

100,000/500,000=100/500=20/100=20%

the naswer is 20%
