Final answer:
Calais makes $11.36 per hour at his normal pay rate. The correct answer is c. $11.23.
Step-by-step explanation:
To find out how much Calais makes per hour at his normal pay rate, we need to calculate his regular pay for 36 hours and then subtract it from his total pay for the week. The regular pay would be the amount he earns for 36 hours multiplied by the regular pay rate. We can write this as an equation: 36 * x = regular pay, where x is the regular pay rate.
Next, we can subtract the regular pay from the total pay to find out how much he earned for the overtime hours: total pay - regular pay = overtime pay. The overtime pay would be the amount he earns for the 6 overtime hours multiplied by the double time rate. We can write this as an equation: 6 * 2x = overtime pay, where 2x is the double time rate (since it is twice the regular pay rate).
Finally, we can add the regular pay and the overtime pay to find the total pay for the week: regular pay + overtime pay = total pay. We can write this equation as: regular pay + 6 * 2x = total pay. Substituting the given values into the equation, we get: 36 * x + 6 * 2x = 545.28.
Simplifying the equation, we have: 36x + 12x = 545.28. Combining like terms, we get: 48x = 545.28. Dividing both sides of the equation by 48, we get: x = 11.36.
Therefore, Calais makes $11.36 per hour at his normal pay rate.
