Olivia works 4 hours more each week than her coworker Lily. Olivia works a total of 32 hours every 2 weeks. How many hours each week does Lily work?

First it's every 2 weeks so divide by 2 to find 1 week and get 16 hours a week then subtract 4 hours cause olivia works 4 more per week and u get 12 hours so Lily works 12 hours a week; )
