^^^^^^^^^^^^^^^^^

Answer 2

Explanation:

r=26

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

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

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

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