Answer:
If the number of hours needed for the job is [tex]4[/tex] hours then he can choose either to be paid for the job or by hour. If he works for more than [tex]4[/tex] hours then he should choose the option of getting paid by the hour.
Step-by-step explanation:
He should choose hourly wage if the number of hours are of a value so that the total paid is more than $50.
Let's take that number of hours worked is [tex]x[/tex]
If,
[tex]12.5*x=50[/tex]
=[tex]x=\frac{50}{12.5}[/tex]
=[tex]4[/tex] hours
Then he can choose either to be paid for the job or by hour. If he works for more than [tex]4[/tex] hours then he should choose the option of getting paid by the hour.
