Question

complete the story so that it can be modeled by the equation $10 + x = 30$.
aiden bought a package of 30 glow-in-the-dark stickers to put on the ceiling in his
room. there were 10 plane
options:
x glow-in-the-dark stickers
30 glow-in-the-dark stickers

Explanation:

Step1: Match equation to story

The equation is $10 + x = 30$, so total stickers = 30, with 10 of one type and $x$ of another.

Step2: Fill the blank logically

The story needs to state the 10 plane stickers plus $x$ other stickers equal 30 total.

Answer:

Aiden bought a package of 30 glow-in-the-dark stickers to put on the ceiling in his room. There were 10 plane glow-in-the-dark stickers and $x$ glow-in-the-dark stickers of a different design.

(Note: The dropdown selection to complete the story is "x glow-in-the-dark stickers", paired with adding a phrase like "and" to connect the 10 plane stickers to this $x$ value to fit the equation $10 + x = 30$.)
