The equation \( A(g) = 15 - 0.50g \) represents the amount of money remaining on a customer's card \( A \) after playing \( g \) games.
- The term \( 15 \) represents the initial amount on the card, which is $15.
- The term \( -0.50g \) indicates that \( 0.50 \) dollars are deducted from the card for each game played.
Based on this interpretation, the correct statement is:
The initial amount on the card is $15, and each game costs $0.50.
