To find the flat fee for the annual golf pass, we can define a linear model based on the information given. The general equation for linear relationships can be represented as:
\[ y = mx + b \]
where:
- \( y \) is the total amount spent,
- \( x \) is the number of rounds played,
- \( m \) is the variable cost per round played (the cost for the golf cart),
- \( b \) is the flat fee for the annual golf pass.
From the problem, we have the points (27, 1,249) and (39, 1,393). We can use these points to find the slope \( m \):
- Calculate the slope \( m \):
\[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1393 - 1249}{39 - 27} = \frac{144}{12} = 12 \]
So the cost per round played (the cost of the golf cart) is $12.
- Now, we can use one of the points to find \( b \), the flat fee. Let's use the point (27, 1249):
\[ 1249 = 12(27) + b \] \[ 1249 = 324 + b \] \[ b = 1249 - 324 = 925 \]
Therefore, the flat fee for the annual golf pass is $925.
The correct answer is B. $925.
