why do you times 8.6x1.5x8? where does the 8 come from?
You said the employee worked 48 hours in a week, right? 40 hours were paid at his regular rate ($8.60/hour or 8.6), and the extra 8 hours (overtime) were paid at time and a half (8.6 x 1.5). Once you know what the overtime rate is, then you multiply it by the number of overtime hours he worked, in this case 8.
In this scenario, the number 8 is derived from the fact that the employee worked an additional 8 hours as overtime. The regular rate of $8.60 per hour represents the employee's normal pay rate. However, for the additional 8 overtime hours, the employee is entitled to time and a half, which means the pay rate is increased by 50% (represented by 1.5).
To calculate the overtime pay, we multiply the overtime hours (8) by the overtime rate (regular rate x 1.5). So, in this case, the calculation would be:
8.6 (regular rate) x 1.5 (overtime rate) x 8 (number of overtime hours) = $103.2
Hence, the 8 is used to represent the additional overtime hours worked by the employee, and it helps determine the total overtime pay.
