Final answer:

To find how much flour the baker needs to make 288 cupcakes, set up a proportion using the given information. The baker needs 36 cups of flour to make 288 cupcakes.

Step-by-step explanation:

To find how much flour the baker needs to make 288 cupcakes, we can set up a proportion using the given information.

In the original recipe, the baker uses 1 1/2 cups of flour to make 12 cupcakes. So, the proportion would be:

1 1/2 cups / 12 cups = x cups / 288 cups

To solve for x, we can cross-multiply and solve for x:

(1 1/2)(288) = 12x

432 = 12x

x = 432 / 12 = 36

Therefore, the baker needs 36 cups of flour to make 288 cupcakes.

Answer is 36 cups flour for 288 cupcakes

We can find the answer using cross multiplication

First change 1 1/2 cups to 1.5 for easy math

1.5c flour / 12 cupcakes = x flour/ 288 cupcakes

1.5 x 288 = 12 x

432 = 12x

36 = x

36 cups flour for 288 cupcakes

You can also find the ratio of flour to cupcakes. 1.5 ➗ 12 cupcakes = .125

Multiply ratio of .125 x 288 cupcakes you get 36 cups flour.
