Problem
Victoria is paid a salary of $\$ 430$ a week at her job. She worked 9 hr of overtime during the holidays, and her weekly paycheck came to $\$ 610$. What is her overtime pay per hour? Victoria makes $\$ \square$ an hour for overtime.
Solution
Step 1 ：Find the difference between her regular salary and her paycheck with overtime: \(610 - 430 = 180\)
