Question 1

The percent decrease in average daily circulation from 1960 to 1970 was approximately:

[Note: From the graph, circulation in 1960 was 650,000 and in 1970 was 440,000]

  • $10\%$
  • $12\%$
  • $20\%$
  • $32\%$✔️
Correct Answer Explanation

Percent decrease $= \frac{\text{decrease}}{\text{original}} \times 100\%$

Decrease $= 650{,}000 - 440{,}000 = 210{,}000$

Percent decrease $= \frac{210{,}000}{650{,}000} \times 100\% = \frac{210}{650} \times 100\% = \frac{21}{65} \times 100\%$

$= 0.3231 \times 100\% \approx 32.31\%$

Therefore, the percent decrease is approximately $32\%$.
