Problem lacks standard daily hours Steps:

• Basic pay rate is $16 per hour, but standard daily hours are unspecified ("working hours a day" is incomplete).
• Overtime at 1.5 × $16 =$24 per hour, but starting after how many hours is unclear ("for working 7 hours a day" is ambiguous).
• Bonus = (12 - 9) units × $32 =$96.
• Without standard hours, regular pay and overtime hours cannot be determined; possible totals vary (e.g., assuming 7 hours: $112 regular +$72 overtime + $96 =$280; assuming 8 hours: $128 +$48 + $96 =$272).

Not enough information.
