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
