Explanation22. According to the table, the number of Valentine’s Day cards sold in 1993 was 900 million, and the number of Thanksgiving cards sold was 42 million. Therefore the number of Valentine’s Day cards sold was \(\frac{900}{42}\), or approximately 21.4 times the number of Thanksgiving cards sold. Of the answer choices, the closest is 20. The correct answer is
Choice A.23. According the table, 155 million Mother’s Day cards were sold in 1993. The card company that sold 40 percent of the Mother’s Day cards sold (0.4)(155) million, or 62 million cards. Since that company priced the cards between $1.00 and $8.00 each, the revenue, r million dollars, from selling the 62 million cards was between ($1.00)(62) million and ($8.00)(62) million, or between $62 million and $496 million; that is, 62 < r < 496. Thus the correct answer is
Choice E.24. According to the bar graph, the annual revenue from all greeting card sales in 1990 was approximately $4.5 billion, and the corresponding total in 1993 was approximately $5.75 billion. Therefore the percent increase from 1990 to 1993 was approximately \(\frac{(5.75-4.5)}{4.5}*100%\), or approximately 28%. The correct answer is
Choice D.25. According to the bar graph, the total annual revenue in 1993 was approximately $5.75 billion. In the question, you are given that the average price per card for all greeting cards sold was $1.25. Therefore the total number of cards sold for all occasions was \(\frac{5.75}{1.25}\) billion, or 4.6 billion.
According to the table, the total number of cards sold in 1993 for the ten occasions shown was 3.9 billion. So the number of cards sold for occasions other than the ten occasions shown, in billions, was 4.6 – 3.9, or 0.7 billion. Note that 0.7 billion equals 700 million. From the table, you can see that less than 700 million cards were sold for each of six of the occasions in the answer choices: Easter, Mother’s Day, Father’s Day, Graduation, Thanksgiving, and Halloween.
Thus the correct answer consists of
Choices C, D, E, F, G, and H.
