1. The problem states Rajesh has 70 and then subtracts a series of amounts: 5, 10, 10, 5, and 20. 2. Start with the initial amount: $70$. 3. Subtract each amount step-by-step: $$70 - 5 = 65$$ $$65 - 10 = 55$$ $$55 - 10 = 45$$ $$45 - 5 = 40$$ $$40 - 20 = 20$$ 4. Therefore, after all the subtractions, Rajesh has $20$ left.
