Example Questions
Example Question #1 : How To Read Graphs
Refer to the above graph. Which of the following comes closest to the percent of increase in population enjoyed by Jones City between 1900 and 1950?
20% increase
60% increase
80% increase
40% increase
100% increase
60% increase
In 1900, the population was about 3,500; in 1950, it was about 5,600. A reasonable estimate of the percent of increase would be
so 60% would be the most reasonable choice.
Example Question #11 : Interpretation Of Tables And Graphs
The above figure shows two black quarter-circles inscribed inside a rectangle. If the black region has area 200, what is the area of the white region (nearest tenth)?
If the radius of each quarter-circle is 
Set 
The area of the rectangle, which we will call 
The area of the white region is the difference of these two areas, or
Example Question #3 : How To Read Graphs
Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period.
Tim wants to know the high temperature for the Sunday of the next week. He does not have access to that information, but he knows that it was higher than those of exactly four of the five previous days, and lower than that of one of them. Which of the following temperatures could have been the high temperature for that day?
Since we are dealing with the day after the last one shown, and we are comparing that day's high temperature to those of the previous five days, we only need to concern ourselves with the high temperatures for Tuesday through Saturday.
Examine the figure below, which shows the high temperature line for those five days.
For the high temperature for the next Sunday to be greater than exactly four of the five and less than the remaining one, the temperature must be strictly between the highest and second-highest high temperatures, which are seen to be 78 and 74 degrees, respectively. That is, if we let 
Of the four choices, only 75 falls in this range.
Example Question #3 : How To Read Graphs
Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period.
Which of the following temperatures occurred at least once on each of the seven days?
The graph is recreated in the figure below, with horizontal lines at the 57, 62, 67, and 72 degree levels.
It can be seen that of the four lines, only the 62 degree line falls between the high temperature and low temperature for each of the seven days. This is the correct choice.
Example Question #4 : How To Read Graphs
Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period. The temperatures at left are given in degrees Fahrenheit.
Temperatures given in degrees Fahrenheit can be converted to the Celsius scale using the formula
Express the lowest temperature of the week in degrees Celsius (nearest whole degree).
As can be seen below, the lowest temperature for the week was 
To convert this to degrees Celsius, set 
Example Question #3 : How To Read Graphs
Refer to the above graph, which shows the high and low temperatures for Kingdom City over a one-week period. The temperatures at left are given in degrees Fahrenheit.
Temperatures given in degrees Fahrenheit can be converted to the Celsius scale using the formula
What was the difference, in degrees Celsius, between the highest temperature and the lowest temperature for the week (to the nearest whole degree)?
As can be seen below, the highest temperature for the week was 
To convert the former to degrees Celsius, set 
To convert the latter, do the same, with 
The difference is
Example Question #12 : Interpretation Of Tables And Graphs
The menu of a local coffeehouse reads as follows:
A boss is treating his employees to drinks. Seven of them want iced tea, five want cafe latte, four want espresso, three want cappucino, one wants Americano, and one wants Turkish coffee. How much will the boss spend, disregarding tax?
Multiply each price by the quantity ordered:
Seven iced teas:
Five cafe lattes:
Four espressos:
Three cappucinos:
Add the $2.39 for the Americano and the $2.09 for the Turkish coffee. The sum:
Example Question #2 : How To Read Tables
The above is an annual income tax table for married couples for a given state.
Mr. Phillips earned $27,287 last year; Mrs. Phillips earned $25,879. How much will the couple pay in income tax for that year (nearest hundred dollars)?
The Phillips's income totaled
This puts them in the 1.3% tax bracket, so they will pay
The correct response is $700.
Example Question #2 : How To Read Tables
The above is an annual income tax table for single persons in a given state.
Grant earned $4,389 per month over a one-year period in his regular job. He also claimed $1,736 in interest income and $3,781 in stock dividends. Based on the above table, how much income tax will he pay (nearest dollar)?
Grant earned, in salary, interest, and dividends:
This puts him in the $40-60,000 range, so he will pay $210 plus 1.3% of his income above $40,000. This will be
Example Question #13 : Interpretation Of Tables And Graphs
The above is an annual income tax table for single persons in a given state.
Mr. Wells, a single man, paid $690 in taxes last year. Which of the following amounts comes closest to his income for the year?
