got it sorry my computer messed up

Vocaloid:

if he wants to spend more time reading than TV, then reading must be > 2 hours

Vocaloid:

Vocaloid:

ok I just read your attachment, let me think

smithm29:

ok

Vocaloid:

red definitely needs to be a dotted line since reading > tv

smithm29:

mhm

smithm29:

so its b or c

Vocaloid:

blue also needs to be a dotted line. if you look at the tip where reading = 2 and tv = 2, you can't have that value

smithm29:

so it has to be c

Vocaloid:

yeah, that's my best bet

smithm29:

k thx

Vocaloid:

if not, then B probably

smithm29:

it was c
