Answer:

Kennedy can make 3 full batches of biscuits.

Explanation:

Kennedy has 8 cups of flour. She covers the countertop and the rolling pin with 1/2 cup of flour. Then she uses 2 1/4 cups of flour for each batch of biscuits she bakes. How many full batches of biscuits can Kennedy make ? Show your work

x = # of batches of biscuits


2(1)/(4)x+(1)/(2)=8

In decimal form:


2.25x+0.5=8

- 0.5 - 0.5


2.25x=7.5

/2.25 /2.25


x=3.33

*Remember, they want us to know how many FULL batches of biscuits Kennedy can make.*

In this case, it would be 3, because 3.33 is not a whole number.

Kennedy can make 3 full batches of biscuits.

Hope this helps!
