Question

A cupcake factory has already used 19.2 lb of flour today. They are now making cupcakes that require 0.5 lb per batch.

Let the total weight of flour be represented by f.

Let number of batches baked be represented by b.

An equation that represents the scenario is f = 0.5b + 19.2

what is the total weight of flour used if they bake 5 batches? (answer as a decimal)

Answer 1

21.7

Explanation:

Answer 2

166.8 pounds.

Explanation:

Let b be the number of batches baked and f be the total weight of flour.

We have been given that a cupcake factory has already used 22.8 pounds of flour today.

They are now making cupcakes that require 8 pounds per batch, so the weight of flour used in b batches will be 8b.

The equation representing the total weight of used flour is given as:

To find the total weight of flour used, when 18 batches are baked we will substitute b = 18 in our given equation.

Therefore, the total weight of flour used in baking 18 batches will be 166.8 pounds.
