Q. Pick the story that can be modeled by the equation

x + 4 = 24

.

\newline

Choices:

\newline

(A)On Earth Day, Mary made a total of

24

cookies. She made

x

flower-shaped cookies and

4

bee-shaped cookies.

\newline

(B)On Earth Day, Mary made

4

batches of cookies. Each batch had

x

cookies. Mary made

24

cookies in all.

Identify Equation Structure: Identify the equation structure and compare with choices. $\newline$ The equation $x + 4 = 24$ suggests that $x$ and $4$ are added to make $24$ .
Analyze Choice (A): Analyze choice (A): Mary made $x$ flower-shaped cookies and $4$ bee-shaped cookies, totaling $24$ cookies. $\newline$ This matches the equation structure: $x$ (flower-shaped cookies) + $4$ (bee-shaped cookies) = $24$ (total cookies).
Analyze Choice (B): Analyze choice (B): Mary made $4$ batches of cookies, each batch had $x$ cookies, totaling $24$ cookies. $\newline$ This implies multiplication, not addition: $4 \times x = 24$ , which does not match the equation $x + 4 = 24$ .
