Diagrams frequently describe benefits or limits using 'up to' (e.g., 'up to 50% off' or 'up to five guests'). Remember this phrase describes a range ending at the stated maximum, so a scenario within that range still qualifies. Distinguish it from 'exactly' or 'at least', which set different kinds of limits.
Synonyms: as much as, a maximum of, not exceeding
