8-75.

Your teacher has offered your class extra credit. She has created two spinners, shown at right. Your class gets to spin only one of the spinners. The number that the spinner lands on is the number of extra credit points each member of the class will get. Study both spinners carefully.

Assuming that each spinner is divided into equal portions, which spinner do you think the class should choose to spin and why?

The spinner of the left earns 20 points only

of the time.

The spinner on the right earnspoints of the time and points of the time. What if the spot labeled “

” were changed to “ ”? Would that make any difference? Now the spinner of the left earns 100 points

of the time.
