t>-2

On average, Sari should read 40 pages per day to meet her goal. (200/5=40)

OpenStudy (texaschic101):

2t + 8 >= -4(t + 1) -- distribute through the parenthesis 2t + 8 >= -4t - 4 -- add 4t to both sides 2t + 4t + 8 >= -4 -- subtract 8 from both sides 2t + 4t >= -4 - 8 -- combine like terms 6t >= -12 -- divide by 6 t >= -2 200/5 = 40 pages per day

OpenStudy (texaschic101):

at least 40 pages per day

OpenStudy (anonymous):

Ty how about this one?

OpenStudy (texaschic101):

15h >= 200 -- divide by 15 h >= 200/15 h >= 13.33 or 13 1/3 hours answer A
