Final answer:
To determine how large a monthly car payment a family can afford, we need to consider their take-home pay and their existing credit payments. The rule of thumb is that the total credit payments should be less than 20% of their take-home pay. In this case, the family has a take-home pay of $3,600 per month and existing credit payments of $122 (Sear's charge) and $110 (VISA). So, their total credit payments are $232 per month. Therefore, the family can afford a maximum monthly car payment of $488.

To determine how large a monthly car payment a family can afford, we need to consider their take-home pay and their existing credit payments. The rule of thumb is that the total credit payments should be less than 20% of their take-home pay. In this case, the family has a take-home pay of $3,600 per month and existing credit payments of $122 (Sear's charge) and $110 (VISA). So, their total credit payments are $232 per month. Let's calculate the maximum monthly car payment they can afford:
20% of $3,600 = $720
Subtracting the total credit payments from the maximum amount:
$720 - $232 = $488
Therefore, the family can afford a maximum monthly car payment of $488.
