1. Cal sold 4,000 gallons per day at a price of $2.189 per gallon. He raised the price 1 cent to $2.199 per gallon, and revenues and profits dropped. His station sold 3,600 gallons per day at $2.199 per gallon. Fixed costs are $250 per day. What is the price elasticity of demand? Can the elasticity be characterized as elastic, inelastic, or neither? By how much did revenues increase or decrease as a result of the change in price? By...

The number of goods sold by “The Local” is in excess of one million per year with deliveries being about 40% of that figure. The amount of goods sold has decreased marginally in recent years. “The Local” is wholly owned but Bianca and her staff have a standard of living to maintain so there is some pressure to raise overall sales whilst keeping costs, particularly delivery costs, in check. Bianca continues: It is your job to use the sample data...

The number of loaves of bread sold per day by an organic bakery over the past...

The number of loaves of bread sold per day by an organic bakery over the past five years can be treated as a random variable that is normally distributed. This distribution has a mean of 77.5 and a standard deviation of 14.4 loaves. Suppose a random sample of 36 days has been selected. Determine the probability that the average number of loaves sold in the sample of days exceeds 80 loaves. First find the standard error of the mean. Now...
