What is algebraic expression that describes the monthly pay?

An algebraic expression that describes monthly pay can be represented as ( P = r \times h ), where ( P ) is the monthly pay, ( r ) is the hourly wage, and ( h ) is the total number of hours worked in a month. If there are additional factors, such as overtime pay or bonuses, the expression can be adjusted to include those variables, for example, ( P = r \times h + b ), where ( b ) represents any bonuses.
