Suppose that you are buying a car for $56,000, including taxes and license fees. You saved $8000 for a down payment. The dealer is offering too two incentives:
Incentive A is $10,000 off the price of the car, followed by a five-year loan at 7.34%.
Incentive B does not have a cash rebate, but provides free financing (no interest) over five years.
What is the difference in monthly payments between the two offers? Which incentive is the better deal?

- Listed below are annual data for various years. The data are weights (metric tons) of imported lemons and car crash fatality rates per 100,000 population. Construct a scatterplot, find the value of the linear correlation coefficient r, and find the P-value using a = 0.05. Is there sufficient evidence to conclude that there is a linear correlation between lemon imports and crash fatality rates? Do the results suggest that imported lemons cause car fatalities?

When Mercedes-Benz hosts a concert, the stage takes up the first 20 yds. The two VIP areas takes up the next 4 yards. After that, there are six ground floor sections. Each ground floor section is divided by aisles that are 5 yards wide. Each chair requires a square of 1 yard x 1 yard.
