From the double line graph, find the difference between the average number of ice-cream cones sold in the two successive years.

 a. 1 b. 3 c. 2 d. 4

#### Solution:

= (10+20+40+50+60)5 = 1805= 36
Average number of cones sold in 1992
[Add the number of cones sold in all the months and divide by the number of months.]

= (20+30+50+20+40)5 = 1605= 32
Average number of cones sold in 1991
[Add the number of cones sold in all the months of 1991 and divide by 5.]

= 36 - 32 = 4
The difference between the average number of cones = average in 1992 - average in 1991
[Subtract.]

The graph shows the comparison of rainfall in Springfield during the second half of the two years 1993 and 1994. How much more rainfall did Springfield get in August 1994 than in August 1993?

 a. 4 in. b. 2 in. c. 1 in. d. 3 in.

#### Solution:

Each point on the line graph indicates the rainfall (in inches) in Springfield during the particular month of the year.

From the graph, the rainfall of Springfield in August 1993 was 1 in. and that in August 1994 was 2 in.

= 2 - 1 = 1 in.
The difference between the rainfall of Springfield in August of the two years = rainfall in August 1994 - rainfall in August 1993
[Subtract the smaller number from the greater number.]

So, the rainfall of Springfield in August 1994 was 1 in. more than that in August 1993.
