George's page contains twice as many typed words as Bill's page and Bill's page contains 50 fewer words than Charlie's page. If each person can type 70 words per minute, after one minute, the difference between twice the number of words on Bill's page and the number of words on Charlie's page is 220. How many words did Bill's page contain initially?

Answer:
200 words
Step-by-step explanation:
G=number of words on george's page b=number of words on bill's page c=number of words on charlie's page george has 2 times as many as bill's age g=2b bills contains 50 less than charlie b=c-50 if each person can type 70 words per minute, after 1 minute (that is an additional 70 words for each person) the difference between twice nmber of words on bill's page and the number of words on charlie's page is 220 so that is after increase of 70 words 2(b+70)-(c+70)=220 and b=c-50 subsittute 2(c-50+70)-(c+70)=220 2(c+20)-c-70=220 2c+40-c-70=220 c-30=220 c=250 charlie had 250 initially b=c-50 b=250-50 b=200 bill had words 200 initially who cares about george
