There is a daily fee for renting a moving truck, plus a charge of $0.50 per mile driven. if driven 48 miles, it costs $64 to rent a truck. write and solve an equation to find the daily fee.

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?
