Key Insights

1. Smartphone users increased dramatically (over fivefold from 400M to 2,050M) while world population only increased about \(13\%\) (6,100M to 6,880M) between 2000 and 2010.
2. The chart visually shows that smartphone adoption accelerated (bars rise sharply), especially after 2006, while population grew at a steady, gradual rate (line almost straight).
3. As a result, the number of smartphone users per 100 people rose from about 6.6 to 29.8, showing rapid penetration of smartphones globally in just a decade.

Step-by-Step Solution

Question 1: Percent Increase in Smartphone Users

Complete Statement:

The percent increase in the total number of Smartphone users from 2002 to 2007 was approximately _____ \(\%\).

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: percent increase
    • Meaning: We are being asked by what percentage the number of smartphone users increased over a period.
    • Relation to Chart: We need to identify the number of users in 2002 and 2007 from the chart.
    • Important Implications: Apply the percent change formula: \(\frac{\mathrm{New - Old}}{\mathrm{Old}} \times 100\%\).
• Statement Breakdown 2:
  • Key Phrase: from 2002 to 2007
    • Meaning: These are our two relevant years.
    • Relation to Chart: We'll use data points from these specific years.
    • Important Implications: Only these two values are needed for the calculation.

What is needed: By what percent did the total number of smartphone users increase between 2002 and 2007?

Solution:

• Condensed Solution Implementation:
  Estimate the values from the chart and use the percent change formula. As answer choices are widely separated, an approximate calculation suffices.
• Necessary Data points:
  Number of smartphone users in 2002 (about 700 million) and in 2007 (about 1350 million).
  • Calculations Estimations:
    Increase = 1350 million - 700 million = 650 million. Percent increase = \(\frac{650}{700} \times 100\% \approx 93\%\).
  • Comparison to Answer Choices:
    \(93\%\) is closest to \(100\%\) (the available choices are \(50\%\), \(100\%\), \(200\%\), \(300\%\)). \(100\%\) is the best answer.

FINAL ANSWER Blank 1: 100

Question 2: Increase in Smartphone Users per 100 People

Complete Statement:

The number of Smartphone users per 100 people increased by approximately _____ from 2000 to 2010.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: users per 100 people
    • Meaning: This describes the rate of smartphone users per 100 people (penetration rate).
    • Relation to Chart: Requires both total users and total population numbers for relevant years.
• Statement Breakdown 2:
  • Key Phrase: increased by
    • Meaning: We are to find the absolute difference between the two rates.
    • Relation to Chart: Subtract the 2000 rate from the 2010 rate.

What is needed: How much did the number of smartphone users per 100 people go up from 2000 to 2010?

Solution:

• Condensed Solution Implementation:
  Estimate the user and population numbers for the specified years and calculate the rates, then take the difference.
• Necessary Data points:
  2000: 400 million users, 6100 million population. 2010: 2050 million users, 6880 million population.
  • Calculations Estimations:
    2000 rate: \(\frac{400}{6100} \times 100 \approx 6.6\) per 100 people. 2010 rate: \(\frac{2050}{6880} \times 100 \approx 29.8\) per 100 people. Difference \(\approx 29.8 - 6.6 \approx 23.2\).
  • Comparison to Answer Choices:
    23.2 is closest to 24 among the choices (6, 12, 24, 30, 36). Therefore, 24 is the best answer.

FINAL ANSWER Blank 2: 24

Summary

Both questions were solved using estimation and simple calculations, matched to answer choice ranges. For question 1, the choice closest to the estimated percentage increase is \(100\%\). For question 2, the increase in users per 100 people rounds to 24. Estimation was sufficient due to the spacing of answer choices.

Question Independence Analysis

The questions are independent: the first concerns percent change in total users over a short period, while the second concerns the absolute rate increase per 100 people over a different period. No answer or method from one is needed for the other.
