Step-by-step explanation: I calculated 5.5 % of 250,000, totaling 13,750. I than multiplied 13,750 by 9 to get 123,750. As the last step, I subtracted 123,750 from 250,000, obtaining a final answer of 126,250 people. I apologize if this is incorrect.
I am not positive for the factoring of each expression but for the distributive property you do 8 TIMES x then 8 times 7 so you would get blank plus blank and so on for the next ones.
