Q:
# I need help on this.Banana Cupcakesmakes 10 cupcakes1 cup granulated sugar cup vegetable oil1 large egg4 tablespoons sour cream2 medium-sized ripe bananas, mashed1 cups all-purpose flour1 teaspoon baking soda teaspoon salt1 teaspoon vanilla extractpinch of nutmegYou will use the recipe above to answer the following questions:This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?How much vegetable oil do you need for 30 cupcakes?How much flour do you need for 30 cupcakes?What is the difference in the amount of vanilla extract you would need for 30 cupcakes?What is the difference in the amount of salt you would need for 30 cupcakes?In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?

Accepted Solution

A:

3, because if it only makes 10 cupcakes, you need to triple it (i.e. 10*3=30); (Assuming it was 1 cup oil) 3 cups vegetable oil; 3 cups flour; the difference is 2 teaspoons; (Assuming it was 1 teaspoon salt) the difference is 2 teaspoons; It would make sense to round the bananas because "medium-sized bananas" depends on your personal opinion, which means it's already rounded and further rounding wouldn't hurt as long as you're careful.
