Let's break this down:
The difference: Something's gotta be subtracted
Twice a number: So 2 times a number, or n
and 3: So we gotta subtract 2n and 3
is 11: The final answer is 11
So altogether is:
2n - 3 = 11

Answer:
Mr. Ali worked for 55 hours.
Step-by-step explanation:
Basic working hours = 40 hours
Total gross wages = $490.15
Overtime wages = $156.75
Total wages as per basic week = Total Gross wages - Overtime wages
Total wages as per basic week = $490.15 - $156.75 = $334.4
Let wages for basic hours = ![\$x](https://tex.z-dn.net/?f=%5C%24x)
![40\times x = \$334.4\\\Rightarrow x = \bold{\$8.36}](https://tex.z-dn.net/?f=40%5Ctimes%20x%20%3D%20%5C%24334.4%5C%5C%5CRightarrow%20x%20%3D%20%5Cbold%7B%5C%248.36%7D)
Let the number of overtime hours =
hours.
Given that the wages for overtime are paid for at time-and-a-quarter.
As per question statement:
![y\times 8.36\times \dfrac{5}{4} = $156.75\\\Rightarrow y = \bold{15\ hours}](https://tex.z-dn.net/?f=y%5Ctimes%208.36%5Ctimes%20%5Cdfrac%7B5%7D%7B4%7D%20%3D%20%24156.75%5C%5C%5CRightarrow%20y%20%3D%20%5Cbold%7B15%5C%20hours%7D)
Total number of hours worked by Mr. Ali = 40 + 15 = <em>55 hours</em>
