4 DS: ask if x+y>0
a)x/(x+y) >0 b) y/(x+y)>0
I think the answer is E
5.PS: bob saved a portion of his income this year and spent all the rest. For each dollar he saved this year, he can get 1+r dollar next year. If bob does not have any income next year and the savings is the only money he has, how much is the proportion he saved this year in terms of r if the money he have next year is half the money he spent this year
the answer I think is 1/(3+2r)
3．X scale and Y scale: x=24, y=60; x=12, y=40。求y=100时，X?
