    Mike works in a toy store. One week, he worked 38 hours and made $220. The next week, he received a raise, so when he worked 30 hours he made $180. How much was his raise (to the nearest cent)?

    First week, Mike earns the following in hours (h)
    38h = 220
    h = 5.79 using our equation calculator
    We call this his old hourly salary

    Next week, Mike earns the following in hours (h)
    30h = 180
    h = 6 using our equation calculator
    We call this his new hourly salary

    His raise is the difference between his current hourly salary and his old hourly salary:
    Raise = New Hourly Salary - Old Hourly Salary
    Raise = 6 - 5.79
    Raise = $0.21
    Mike got a 21 cent hourly raise
