jim_thompson5910 · Answer

where is the open circle located? over the 3? or the 4?

clalgee · Answer

the 4

jim_thompson5910 · Answer

ok that means that if 

x = amount of money left in the wallet

then

x > 4

jim_thompson5910 · Answer

so is x = 2 a solution to x > 4 ?

clalgee · Answer

Yes it is. Right?

jim_thompson5910 · Answer

well let's check

x > 4

2 > 4 ... replace x with 2

is that true?

anonymous · Answer

he's asking if 2 is a bigger number than 4...is it?

clalgee · Answer

Nope, it's smaller than four

jim_thompson5910 · Answer

so there's no way she has $2 in her wallet

this because the amount of money she has in her wallet must be larger than $4

clalgee · Answer

Right. She can't have less than $4 if she has more than it. It woundn't make sense if she did

jim_thompson5910 · Answer

exactly
