1 A 2-pound bag of sugar contains 227 one-teaspoon servings and costs $249. A batch of muffins uses
cup of sugar. How many whole batches can you make if you use as much of the sugar as possible? What is
the cost of sugar for each batch? (1 cup = 48 teaspoons; do not consider leftover sugar in the cost
calculation.)

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
