1)BOWLING BALLS
.
Percent of all people who are bowlers=(40/90)(100%)=44.44%
Percent of bowlers who own ball=(3/16)(100%)=18.75%
Percent of all people who own ball=(.4444)(.1875)(100%)=8.33%
.
(192)(0.0833)=16
ANSWER: Out of 192 people, you would expect 16 to own a bowling ball.
.
2)COSTUMES:
.
(4yds)(3ft/1yd)(8 costumes/4 feet)=24 costumes
.
ANSWER: The designer can make 24 costumes with 4 yards of fabric.
