Answer:
1. 30 student
2. 120 student's didn't vote
3. 7 quarters
Explanation:
1. first, see how many games can be played:
45÷3 = 15
then, multiply the number of games by two because 2 students can play per game
15 • 2 = 30
2. first, figure out what percent of students did not vote:
100 - 60 = 40%
then, multiply the number of students total (300) by the decimal of the percent that did not vote to find the number of students who didn't vote:
300 • .40 = 120 student's didn't vote
3. first, find how much 9 dimes is:
1 dime = $0.10
9 dimes = 9 • $0.10 = $0.90
then, find how much money kerry had:
$2.65 - $0.90 = $1.75
finally, find out how many quarters kerry had by dividing the amount of money she had by the worth of a quarter:
1 quarter = $0.25
$1.75 ÷ $0.25 = 7 quarters
