Kiki made 10 cucumber sandwiches and 8 egg sandwiches for the tea party. Each cucumber sandwich was cut into 4 triangles. Each egg sandwich was cut into 2 rectangles. If her guests ate 28 triangles and 12 rectangles, how many slices of bread did they eat?
Think hard. Detailed solution:
26
The guests ate 28 / 4 = 7 cucumber sandwiches.

The guests ate 12 / 2 = 6 egg sandwiches.

They ate a total of 7 + 6 = 13 sandwiches.

They ate a total of 13 x 2 = 26 slices of bread.

Final answer: 26
