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 100
So, Tonisha has to make at least $100 in revenue

Speed = distance / time
Tuesday: speed = 2.4km / 18 minutes = 0.13 km per minute
Friday: speed = 1.8 km / 12 minutes = 0.15 km per minute
0.15 is larger than 0.13 so she ran faster on Friday.
