these three days is to earn an average of between
- 00:22
two hundred forty two hundred sixty dollars today which of
- 00:24
the following inequality should he solve in order to determine
- 00:27
the values of x that will allow him to meet
- 00:30
his goal And here the pencil answer well looks like
- 00:35
jabari is making some fat stacks Well good for him
- 00:38
We're told how much he raped him yesterday and today

two hundred plus two fifty plus the x by three
- 01:03

that this result needs to be between two hundred forty
- 01:10
in two hundred sixty dollars So yeah that looks exactly
- 01:14
like our answer choice D and well that's Our answer
- 01:18
If jabbar is really not sure about the math you
- 01:21
can spend some time plugging in a few numbers just
- 01:23
to double check But he has other things to do 00:01:25.562 --> [endTime] like roll around his giant pile of cash
