Lashonda found a recipe that makes 2 1/2 dozen cupcakes and requires 1/4 cup of vegetable oil. If she makes 90 cupcakes for a family reunion picnic, how much vegetable oil will she need?

How many dozen are in 90? How will you find out?

Once you find that number, then multiply by 0.25 cup (1/4 cup), and see what happens.

Let us know.

Sorry for not responding, I think I have to divide 12 into 90 which would give 7.5...7.5 x 0.25= 1.875. Now what /Writeteacher?

. . . you there?

2.5 dozen = 28

.25/28 = x/90

To find x, multiply both sides by 90 and then divide by 28.

To find out how much vegetable oil Lashonda will need, we first need to determine the ratio of cupcakes to vegetable oil.

The given information states that the recipe makes 2 1/2 dozen cupcakes. Since a dozen is equal to 12, we can calculate the total number of cupcakes as follows:

2 1/2 dozen cupcakes = 2 x 12 cupcakes + 1/2 x 12 cupcakes = 24 cupcakes + 6 cupcakes = 30 cupcakes

Now, we have the information that the recipe requires 1/4 cup of vegetable oil to make 30 cupcakes.

To find out how much vegetable oil Lashonda would need to make 90 cupcakes, we can set up a proportion:

30 cupcakes require 1/4 cup of vegetable oil
90 cupcakes will require x cups of vegetable oil

We can solve this proportion by cross-multiplying:

30 (cups of vegetable oil) = 1/4 (cup of vegetable oil) * 90 (cupcakes)

Now, let's solve for x:

30 cups of vegetable oil = (1/4) * 90
30 cups of vegetable oil = 22.5

So, Lashonda will need 22.5 cups of vegetable oil to make 90 cupcakes for the family reunion picnic.
