Question

I NEED HELP PLEASE ON THIS 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 marbles 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.

What is the minimum whole number of times they need to be rewarded so they can have a party?

times

Answer 1

Ok so as soon as you stablished that there's 24 in the jar right now. she puts in 3 at a time then you can express it like this:
24 + 3x ≥ 100
The only thing you need to have in mind is to solve for x and round to the nearest whole number.
Hope this helps a lot
