In the graph what information does the bottom row of pizzas give?

Co-ed residence hall ordered 33 pizzas

Explanation

We will count the number of complete pizza symbols that appear in the bottom row of the graph, and we will estimate what fractional part of a pizza symbol also appears in that row.  The key indicates that each complete  pizza symbol represents one dozen (12 pizzas).

The bottom row contains 2 complete pizza symbols and what appears to be \( \frac34 \) of another.  This means that the co-ed residence hall ordered 2 • 12, or 24 pizzas, plus approximately \( \frac34 \) of 12, or about 9 pizzas.  This totals 33 pizzas.
