Question

Aubrey needs 2.4 pounds of flour for birthday cakes and 3.75 pounds of flour for wedding cakes. If she plans on baking 27 birthday cakes and five wedding cakes how many pounds of flour which she need? Round to the nearest 10th of a pound.

Answer 1

To find the total amount of flour needed, we need to multiply the amount of flour needed per cake by the number of cakes for each type.

For birthday cakes:
2.4 pounds of flour * 27 cakes = 64.8 pounds

For wedding cakes:
3.75 pounds of flour * 5 cakes = 18.75 pounds

Therefore, Aubrey will need a total of approximately 64.8 + 18.75 = 83.55 pounds of flour for the birthday and wedding cakes. Rounded to the nearest tenth of a pound, she will need 83.6 pounds of flour.
