Use the 24A-C1 student paper, v0.1 and a pencil. There is no answer box and nothing to submit here. The screen explains; your paper holds your work.

1. Mai’s model · front, problem 1. Read the story and identify the rate and starting amount. Click Show the linear model. Move the time slider to connect an input time to an output water level. Click Show the condition to compare that changing output with the fixed target.
2. One boundary · front, problem 1. Follow “exactly 36” and “at least 36” together. Think through the next operation before revealing it. Compare the point and ray. The optional time buttons check one time in both conditions.
3. Ryan together · back, problem 2. Build and solve the inequality on paper. Reveal one complete line at a time to check your work.
4. Ashley on paper · back, problem 3. Try the problem independently. Then reveal, compare, and keep your corrections.

The large green button tells you exactly what the next click will show. Steps never advance automatically. Back hides the newest line. Choosing a section starts it again with its worked answer hidden.

Paper pause covers the worked solutions and displays the current paper task. Return to the same step when ready. It does not put later reveals into a paused state.

Motion changes animation speed only. No animation shows the same complete mathematics immediately. Replay motion repeats the current visual emphasis. Changing tabs or opening help finishes motion without hiding a step.

Full screen enlarges the Studio if the browser supports it. Otherwise use the browser’s full-screen control. Escape leaves full screen or closes a dialog.

Keyboard: Tab between controls; Enter or Space activates buttons. Arrow keys move the time slider when it has focus. Away from controls, ← and → move between steps, and R replays motion.

This is a learning companion, not an assessment tool. Its graphs and checks do not add a new requirement to every ALEKS or ELO answer.
