Mrs. Morton has a special reward system for her class. When all her students behave well, she rewards them by putting 3 marbles
into a marble jar. When the jar has 100marbles or more, the class has a party. Right now, the jar contains 24 marbles. Let r represent the number of additional times the class is rewarded. Write an inequality to determine how many more times the class needs to be rewarded in order to earn a party.
Divide 100 by 3 to get the amount of TOTAL times you put marbles in the jar. Then divide 24 by 3. 24 divided by 3 is 8. Subtract 8 from the total amount of times needed to reach 100 marbles. After you have done that step, add one because 100 divided by 3 is 33.333333. Since you cant put a fraction of a marble in the jar, you have to add 1 more marble.
