Mrs. Morton has a special reward system for her class. When all her students behave well, she rewards them by putting 3 marbles
Olin [163]

Answer: 24+3r\geq100

r=26


Step-by-step explanation:

Given: Mrs. Morton rewards her students on behave well by putting 3 marbles into a marble jar.

If the jar contains 24 marbles. and r represent the number of additional times the class is rewarded then the required equation will be

24+3r\geq100

If we solve it, we will get the minimum the jar contains 24 marbles.

To solve equation, subtract 24 from both sides, we get

3r\geq100-24\\\Rightarrow3r\geq76\\\Rightarrow\ r\geq\frac{76}{3}\geq25.333\approx 26

Hence, the minimum whole number of additional times they need to be rewarded so they can have a party=26
