# Three complete constructed practice prompts

Before opening the answer key, write a short note for each input. Criteria: correct unit; exact snapshot/period; warranted arithmetic; explicit unknowns. Record allowed help and preserve your first attempt. No real learner is represented.

L1: same account; 1,200 followers on 31 October 2026; 90 new follows during October; unfollows not supplied. Write what is supported and what cannot be inferred. Do not assume the missing losses are zero.

L2: same account, complete flows, no other adjustments; start 1,000, gains 90, losses 30, end 1,060. Write net change and the change relative to starting stock, with the stated conditions.

L3: same post and measurement window; 80 reactions plus comments, 2,000 impressions. Write the ratio and whether it establishes the percentage of distinct people who responded.

Choose an actual later fresh case for your own work, with permitted input and the same criteria. This packet does not record that you attempted or learned anything.
