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? Let's be accurate as possible.
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.
The answer: 26.
