8.If the amount of carbon dioxide (CO2) in a workplace is greater than 1,000 parts per million (ppm), it can cause drowsiness and complaints of stale air. Write an inequality to show the amount of (c) in parts per million that would cause drowsiness and complaints of stale air. Begin the inequality with c
a=c > 1000
9.The number of tomato plants to fit within a garden is 80. Write an inequality that expresses how many plants you can plant within the designated garden area.

14.How many suitcases averaging 25 pounds apiece can be loaded onto a plane that can hold a maximum of 1,750 pounds of storage? If s represents the number of suitcases, how would you write an inequality expressing this situation?
25s≤1,750
15.Stefani needs to earn at least $250 for her trip to the upcoming softball tournament. She babysits on Saturday night and earns $48. Write and solve an inequality to show how much more Stefani needs to earn. Show your work.
A=Stefani has already earned $48, and she needs to earn at least $250 in total. So, the inequality representing this situation is 48+e≥250 To find out how much more Stefani needs to earn, we can solve this inequality for e by subtracting 48 from both sides: e≥250−48.
Simplifying the right side gives: e≥202
So, Stefani needs to earn at least $202 more to have enough for her trip to the softball tournament.
I promise these are the right answers I had gotten an 88, so I want you to git a 100 ok, so please believe me I had gotten an 88 for getting two wrong but you guys deserve a 100. ; )
