Look for the pattern in the free toppings. The difference between 2 and 5 is 3. The difference between 5 and 7 is 2. So, the pattern is 3, 2, 3, 2. That means that the next number of free toppings (for 6 scoops) would be 12 + 3, or 15, and the next (7 scoops) would be 15 + 2, or 17.
- South Orange School Pet Owners for Dogs vs. Cats (2002–2008)
- Weekly Rainfall.
- Go to the Week 3 mark. There were 12 inches of rainfall for Seattle—each mark is two from the last. Multiply 12 by 100, because the axes label tells you that each mark is centimeters × 100: 12 × 100 = 1,200. There were 8 inches of rainfall for Portland—each mark is two from the last. Multiply by 100: 8 × 100 = 800. Now, subtract to find the difference: 1,200 – 800 = 400 centimeters.
- The lines are closest together at Week 6.
- The lines are farthest apart at Week 4.
- 35%. Bill's BBQ Joint spends 35 cents, which is 35% of the total dollar.
- 20 cents. Remember, a pie chart represents 100%, in this case a dollar, or 100 cents. Add up all the given amounts to find how much was spent on all advertising, except online: .21 + .23 + .12 + .10 + .14 = .80. That leaves 20 cents.
- Television. Bill's BBQ Joint must love the camera because they spend .23 of every dollar on TV advertising.
- Repairs Required during First Three Years for MP3 Players (per 100).
- Five MP3 players.
- The key tells you that each symbol represents five MP3 players. The row for Brand A contains six more symbols than the row for Brand T. Multiply 6 by 5 to get 30 more sets per hundred.
- Percent is a fraction of 100. This pictograph displays repairs per hundred MP3 players sold, so it actually shows percents and each symbol represents 5%. Brand Z has eight symbols in its row. So, 8 × 5% = 40%. This is the percent of repairs on Brand Z during the first three years.
- Be careful! This is a trick question. The pictograph contains no information about sales, so there is not enough information to answer this question.
