1-3. The coefficient of "Price" is 2.559. This means that...

a. You pay 2.559 dollars more for Ales beer than for Lager beer

b. A Stout type beer costs 2.559 dollars per bottle

c. When the number of calories per bottle (of any type) increases by 1 calorie, the

price increases by 2.559 dollars.

d. None of the above

1-4. An Ales bottle costs $7.45, and contains 4.8% alcohol. A Stout bottle costs $C and has 3.7% alcohol. If they have the same calorie level, find 'C'. (to calculate use, for example, 4.8 for the percent, not 0.048!!).

1-5. What is the estimated difference in the number of calories between a bottle of Ales beer and Lager beer, if they are priced the same and have the same amount of alcohol. Observe the equation and make a conclusion. Enter your answer in the "Answers" sheet.

1-6. Bottle 1 and bottle 2 are compared. Bottle 1 is Ales type beer, contains A% of alcohol, and costs $P. Bottle 2 is Stout type beer, contains (A+0.5)% alcohol, and costs $(P-1.5). If bottle 1 is predicted to have 105 calories, how many calories are predicted for

bottle 2?

a. Can't answer. 'A' and 'P' are unknown.

b. 105 + 17.88(A+0.5) + 2.559(P-1.5) - 19.42

c. 105 + 17.88(0.5) - 2.559(1.5)

d. None of the above
