    18. Maurice earns $12.50 per hour for the first 40 hours he works each week. For each hour beyond 40 that he works in 1 week, Maurice earns $18.75 per hour. Last week Maurice earned $931.25. How many hours did Maurice work last week?
    Choice J

    Let the number of extra hours Maurice worked beyond 40 hours be E:

    $12.5 × 40 + $18.75 × E = $931.25

    ⇒ E = 23

    ⇒ Total hours = 40 + 23 = 63 hours
