Question

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 100 or more marbles, the students have a party. Right now, the jar has 24 marbles.
Write an inequality to determine the number of additional times, r, Mrs. Morton could reward the class in order for the students to have a party.

Answer 1

Answer: 24 + 3r >= 100

Step-by-step explanation:

24 is the constant (number of current marbles)

We don’t know how many times of acting good to get to 100 (unknown)

Each time class is good you get 3 marbles

At 100 or more you get a party.
