Question

Price of eggs and milk: The following table presents the average price in dollars for a dozen eggs and a gallon of milk for each month from March through December

2006. Use a TI-84 calculator to answer the following.

Dozen Eggs	Gallon of Milk
2.17	3.87
2.20	3.78
2.07	3.80
1.93	3.76
1.92	3.77
2.01	3.96
1.85	3.89
1.98	3.77
1.86	3.66
1.84	3.73

If the price of eggs differs by $0.35 from one month to the next, by how much would you expect the price of milk to differ? Round your answer to at least two decimal places.

Answer 1

from above:

expected change in the price of milk =0.35*slope =0.35*0.2156 =$ 0.08
