Problema Solution

Kristina makes $8.50 per hour. She makes double time for every hour that she works on Saturday. If she works forty hours during the week and earns $425, how many hours did she work on Saturday.

Answer provided by our tutors

5 hours.


$8.50 × 40 hours = $340


$425 - $340 = $85


$8.5 times double time = $17.00


$85 ÷ $17.00 = 5 hours
