Mixed exhibits

Opening your lesson

Ten mixed questions on new exhibits, all for one fictional grocer, Lumen Grocers. Read the title, the units and the footnotes first, then answer.

Several questions carry a trap from the unit: a total row that counts a subtotal twice, a footnote that changes the unit, an indexed line and a market map. Aim for about a minute each.

Before you calculate, say:
  "This is ___ in ___ (unit), by ___, for ___ (period)."

One sentence of reading saves most exhibit mistakes.
