Answer 6

Figure out which two categories add up to 49%. Then see the percentages of the same categories the next year. Then take that percentage and multiply it by 45,000. Look at savings and mortgage. One is 24% and the other 25% (in 1989) so in 1990 the percentages are 27 and 12 or 39. So take .39*45000=17750

Answer 7

For B, well at 10% increase to 25000 is .10*25000+25000=27500. So you have 45000-27500=17500
So you need 25000*x=17500
x=.7 which means that 17500 is 70% of 25000. Or, there is a 30% decrease.

we took it away from 45000 because thats the endpoint year
and i understand that if we take that amout and divide it by what they orignally had we can find the percentage of what that have and therefore find the percentage amout it decreased by
