Each week Jaime saves $50. Every two weeks she spends $46 of her savings on a nice lunch with her mum. How long will it take her to save $135?
Jamie saves 50 * 2 = $<T>multiply(50, 2)=100 every two weeks.
After the lunch with her mum, Jamie saves $100 - $46 = $<T>subtract(100, 46)=54 every two weeks.
Jamie saves $54 / 2 = $<T>divide(54, 2)=27.0 per week.
Jamie will need 135 / 27 = <T>divide(135, 27)=5.0 weeks to save enough.
