Question

marjorie made 26 cookies. after a few days, there were 19 cookies left. fill in the missing values in the bar model to represent the scenario. use a c to represent the unknown value. then determine how many cookies were eaten. \square cookies were eaten.

Explanation:

Step1: Define the equation

Let \( C \) be the number of cookies eaten. The total cookies made is 26, and the remaining is 19. So the equation is \( 26 - C = 19 \).

Step2: Solve for \( C \)

To find \( C \), we rearrange the equation: \( C = 26 - 19 \).

Step3: Calculate the result

\( 26 - 19 = 7 \).
