I just wanna make sure the choices.
A. p is LESS THAN 11
B. p/11 is LESS THAN OR EQUAL TO 5
C. 11p is LESS THAN OR EQUAL TO 140
D. 11p is GREATER THAN OR EQUAL TO 140
OpenStudy (calculusxy):
Are these correct?
OpenStudy (anonymous):
Yes.
OpenStudy (calculusxy):
Perfect :)

When we say at least, usually we mean greater than because it can be the same amount or it can be more than that.

When we say at most, we can mean less than because there is a max amount and you can't exceed it.
OpenStudy (calculusxy):
Now Jessica can earn $140 or even more than that.
OpenStudy (calculusxy):
Mind that it says "at least".
OpenStudy (calculusxy):
Can you find what the answer is?
OpenStudy (calculusxy):
When she earns $11, we might wanna find how many hours she works. That way, we can help knowing what might equal to $140 or might be more than that.
