Practice 4

  1. 35%. Bill's BBQ Joint spends 35 cents, which is 35% of the total dollar.
  2. 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.
  3. Television. Bill's BBQ Joint must love the camera because they spend .23 of every dollar on TV advertising.

Practice 5

  1. Repairs Required during First Three Years for MP3 Players (per 100).
  2. Five MP3 players.
  3. 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.
  4. 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.
  5. Be careful! This is a trick question. The pictograph contains no information about sales, so there is not enough information to answer this question.
