Answer 1

Answer:

Step-by-step explanation:

1) Let x represent the sale price.

normal price = $39.95. This week they are on sale for 25% off the regular price. The amount taken off is

25/100 × 39.95 = 9.9875

Sale price = 39.95 - 9.9875 = $29.9625

2) number of games played by the tigers is 11 + 4 = 15

Percentage of games won is

11/15 × 100 = 73.3%

number of games played by the cubs is 10 + 3 = 13

Percentage of games won is

10/13 × 100 = 76.9%

3) increase in stock price = 61.5 - 52.63 = $8.87

Percentage increase = 8.87/52.63 × 100 = 16.85%

4) if 28 percent of seven graders went

to a movie theater over the weekend and there are 800 students in the seventh grade, then the number of seven graders that saw

the movie is

28/100 × 800 = 224
