1. **State the problem:** Chu earns 50 dollars and puts 10 dollars into savings. We need to find which statement about the fraction of every dollar saved is true. 2. **Formula and explanation:** The fraction of each dollar saved is $ \frac{\text{savings}}{\text{earnings}} = \frac{10}{50} $. 3. **Simplify the fraction:** $$ \frac{10}{50} = \frac{\cancel{10}}{\cancel{50}} = \frac{1}{5} $$ 4. **Interpretation:** This means Chu saves 1/5 of every dollar he earns. 5. **Answer:** Statement A is true: 1/5 of every dollar Chu earns is put in savings.
