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.
Will the students have a party if Mrs. Morton rewards them
\[31\] additional times?
Choose 1 answer:
A
Yes
B
No

Answer 1

Inequality: 24 + 3r ≥ 100.

Solve: 3r ≥ 76 → r ≥ 76/3 ≈ 25.33, so r must be at least 26 times.

For r = 31: 24 + 3(31) = 117 ≥ 100, so yes. Answer: A.
