A company pays $20 per hour for up to 6 hours of work, and $30 per hour for
scoray [572]

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.
