Question

if the electricity bill increased from $10,000 to $13,000 in a year, to the nearest whole percent, what was the rate of increase? I need to see how to work this one. I divided 3,000 by 10,000 and got.3 What is that in percent and is this even the right way?

Answer 1

You got 0.3. To find the percent, multiply by 100 -- or move the decimal point two places to the right.

0.3 = 30%
