Jaquez earns money by doing yard work. it takes her an average of 3 hours to pull weeds and an average of 2.5 hours to mow the lawn. she can work no more than 8 hours a day. she charges $50 to weed and $65 to mow the lawn. she needs to cover her expenses of $120 to make a profit. write a system of inequalities that would determine how many flowerbeds and lawns he could complete on a given day. (note – you do not need to solve, just write the system and label the variables you use).

Create a real-life situation and create a system and show how it might be modeled algebraically with a system of equations (or inequalities) show all work include a few sentences explaining the situation, your variables of choice and what each represents, and how you would set it up and solve it algebraically. !

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
