Question

Dwayne takes care of horses at the Silver Spur Ranch. The ranch has a red barn and a gray barn. Together, the barns hold a total of 30 horses. The red barn holds 18 horses.
Let g represent the number of horses the gray barn holds. Which equation models the problem?
g–18=30
g+18=30
Solve this equation to find the number of horses the gray barn holds.
horses

Answer 1

To model the problem, we need to understand the relationship between the number of horses in the red barn and the gray barn.

We know that:
- The total number of horses in both barns is 30.
- The red barn holds 18 horses.
- Let \( g \) represent the number of horses in the gray barn.

The equation that represents this situation is:
\[
g + 18 = 30
\]

Now, we can solve for \( g \):

1. Subtract 18 from both sides of the equation:
\[
g = 30 - 18
\]
2. Calculate the right side:
\[
g = 12
\]

So, the gray barn holds **12 horses**.
