Answer 2

Answer:

153 ounces of sugar will be needed.

Step-by-step explanation:

We will use unitary method to calculate the amount of sugar to make 255 cupcakes by Amanda

∵ To make 75 cupcakes amount of sugar needed = 45 ounces

∴ To make 1 cupcake amount of sugar will be needed = 45/75

∴ 255 cupcakes will need amount of sugar = (45/75)×255

                                                                        = (0.6) × 255

                                                                        = 153 ounces

Therefore 153 ounces is the answer.
