If Shyniyah wants to have $200, and she already has $15, you need to subtract $15 from the $200.
200-15= $185
You gain $8 every hour you work and you want to earn $185. So you divide $185 by $8
185/8= 23.125
You will need to round up because you need to work a full hour to earn the $8. So she will need to work 24 hours to earn a total of $200.
If am not exactly sure how to graph it though. Sorry. But if I were you, I would try graphing 8+15 or 23 then 31 then 39. Just keep adding 8 until you get to $200 or more. Again I am sorry if this is wrong because this is how I would answer it.
