Ok, so I could be wrong, but you take 52,070 - 46,020 to get the population increase. (6,050) then multiply it times 8 to get to the population of 2020. for B, just do the same thing, but you'll have to subtract 2020 from 103495 to get your number you need to multiply. (6,050 times ____) Again, I could be totally wrong, but that's how I would do it.
