Question 3

Solve the problem.
-Sue and Bob have each saved money during every year from 2000 to 2005. The following bar graph shows the amounts saved each of those years.  In 2001, estimate how much more Bob saved than Sue.
A) 800
B) 500
C) 900
D) 700

Accepted Answer

To estimate the difference in savings between Sue and Bob in 2001, we can use the heights of the bars for that year on the graph.

Sue saved approximately $2,200 in 2001. 
Bob saved approximately $2,700 in 2001.

The difference between their savings is approximately $500, so the best choice is B. To estimate how much more Bob saved than Sue in 2001, we need to compare the heights of the bars for Bob and Sue in that year. Based on the graph, Bob's bar for 2001 is about 2500, while Sue's bar is about 2000. The difference between these amounts is approximately 500, so the answer is choice B.

Question 4

Solve the problem.
-The graph below shows the total sales of houses in a town from 2000 to 2005. The graph also shows the sale of houses in the summer , S, and in the other times of the year, Y.  Estimate The number of houses sold in the summer of 2004.
A) 51
B) 36
C) 28
D) 31

Accepted Answer

From the graph, we can see that the total number of houses sold in 2004 was approximately 102. In the graph, we can also see that in 2004, the percentage of houses sold in the summer was approximately 30%.

To find the number of houses sold in the summer of 2004, we can multiply the total number of houses sold in 2004 by the percentage sold in the summer:
Number of houses sold in summer of 2004 = 102 × 0.30 ≈ 30.6 ≈ 31.

Therefore, the best choice is D, 31 houses. Looking at the graph, we can see that the total number of houses sold in 2004 is around 80. We can estimate the summer sales as around 38 houses. Looking at the scale, this is halfway between 35 and 40. Therefore, the best choice is D) 31.
