Answer 1

Question1)d question2)B

Answer 2

Question 1) D The temperature dropped 4 degrees each hour for 5 consecutive days.

Question 2) B Alana needs 4 1/2 more cups of sugar.

Explanation:

Question 1) Since the 4 is negative, this means that something needs to be decreasing. The temperature is the only example in which this is the case.

Question 2) If one pumpkin pie calls for 1 1/4 cups of sugar, four pumpkin pies calls for 5 cups of sugar: 4*1 1/4. Since Alana already has 1/2 cup of sugar, 5-1/2=4 1/2.
