Give the step-by-step reasoning process and then the final answer. 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?
User
Jamie saves 50 * 2 = $100 every two weeks. After the lunch with her mum, Jamie saves $100 - $46 = $54 every two weeks. Jamie saves $54 / 2 = $27 per week. Jamie will need 135 / 27 = 5 weeks to save enough.
The final answer: 5.
