The algebraic expression for the overtime hours after 6 hours is (6 + y) 30.
<h3>
Algebraic expression</h3>
This is a system for computating mathematical expression using letters or other symbols to represent numbers, with rules for manipulating these symbols.
- Hourly wage for 6 hours = $20 per hour
- Overtime wage after 6 hours = $30 per hour
- Total hours worked = x
x = (Hourly wage for 6 hours × $20 per hour) + (Overtime wage after 6 + y hours × $30 per hour
x = (6 × 20) + (6 + y) 30
x = 120 + 180 + 30y
x = 300 + 30y
The expression for the overtime hours is (6 + y) 30.
