Reasoning and answer: Susan needs to make 30 / 2 = 15 batches of the recipe. Therefore, she will need 15 * 4 = 60 potatoes. She will also need 1 * 15 = 15 teaspoons of salt. Thus she will have to buy 15 / 5 = 3 containers of salt. Therefore, she will spend 60 * $.1 = $6 on potatoes and 3 * $2 = $6 on salt. Thus, she will spend $6 + $6 = $12 on food.
The answer: 12

Reasoning and answer: The 6 triangles have 3 sides each, for a total of 6 * 3 = 18 sides. The 4 squares have 4 sides each, for a total of 4 * 4 = 16 sides. The 2 hexagons have 6 sides each, for a total of 2 * 6 = 12 sides. The total numbers of sides is 18 + 16 + 12 = 46 sides.
The answer: 46
