       850w > 7500 + 300w
       850w < 7500 + 300w
       850w ≥ 7500 + 300w

To make a profit, he needs to pay recover the original 7500 + the 300 per week he spends. So the sales * week needs to be bigger than that.

answers could be 
12 weeks
       13 weeks
       14 weeks
       15 weeks

anonymous · Answer

i think its 13 weeks what do you think?

texaschic101 · Answer

850w > 7500 + 300w (subtract 300w from each side)
850w - 300w > 7500
550w > 7500 (now divide by 550)
w > 7500/550
w > 13.6
hmmm...not sure if it is 13 or 14, let me check...

850(13) > 7500 + 300(13)
11050 > 7500 + 3900
11050 > 11400 (wrong)

850(14) > 7500 + 300(14)
11900 > 7500 + 4200
11900 > 11700 (correct)

It is 14 weeks
