Hi its me LazyBear you might know me from Twitch. My sister needs help with her homework and i have to go pick-up my friend. So if you could help my sister with math i would be very happy. (Its not that hard) The questions are if 160,000 divided by n=4 find n. The next one is solve nx50=500. Its not that difficult but I gotta leave. Thank you so much! Bye :)

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
