Practice 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.
Practice 5
 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.
