To develop a linear model for this scenario, we can define the following variables:
- Let \( C \) be the total cost.
- Let \( g \) be the cost per game.
- The fixed cost for the game card is $3.50.
- Merari plays 15 games.
The relationship can be expressed with the following equation:
\[ C = 3.50 + 15g \]
We know that Merari's total cost, \( C \), is $14.75. Thus, we can set up the equation:
\[ 14.75 = 3.50 + 15g \]
Next, we solve for \( g \):
- Subtract 3.50 from both sides:
\[ 14.75 - 3.50 = 15g \]
\[ 11.25 = 15g \]
- Divide both sides by 15 to find \( g \):
\[ g = \frac{11.25}{15} \]
\[ g = 0.75 \]
Thus, the amount per game that Merari has to pay is $0.75.
