I think -5, I'm not sure but I think it's -5.
Answer:
x - 31
69
Tonisha has to make at least $100 in revenue
Step-by-step explanation:
Set up the inequality:
x - 31 represents her profit
Since she wants to make at least $69 a day, use
69
So, the inequality is x - 31
69
Then, solve for x to find how much she has to sell:
x - 31
69
x
100
So, Tonisha has to make at least $100 in revenue
= 5+ (5x+20)<20
5x +25<20
5x< -5
x< -1
Okay, so you're going to go along the line that goes side to side, and then find positive 2. It'll be on the right side. From there, go half way in and insert a line going up and down.
Bam! You've got yourself x= 2.5 graphed!
