According to the 2000 Census, 222,030 people lived in Plano, Texas, and 997,790 people lived

in Richmond, Virginia. How many more people lived in Richmond
I think it is 1,219,820 HELPPP

how many more is 10 than 7?

To get that, you subtract 7 from 10, right? 10-7 = 3

I have no idea (since you didn't show any work) how you got your answer, since

997,790 - 222,030 = 775,760

hmmm I'm thinking A but I don't know
