Standard daily hours ambiguous for overtime

Steps:

• Calculate bonus: 25 units produced - 20 standard units = 5 excess units × $4/unit =$20.
• Basic pay: $15/hour × standard daily hours (unspecified).
• Overtime pay: (10 - standard hours) × $15 × 1.25.
• Total pay = basic pay + overtime pay + $20 bonus.
• Not enough information on standard daily hours to compute total.

Why A is correct:

• Not enough information to verify exact pay; A assumes a specific standard (e.g., ~4 hours) yielding ~$192, but problem lacks definition.

Why the others are wrong:

• B assumes erroneous 25% premium on daily basic ($180 +$20 = $200).
• C overcounts bonus or hours (e.g., all 25 units at $4 =$100 + inflated hours).
• D greatly overcounts (e.g., 20 hours basic or full bonus on all units).

Final answer: A
