1. **State the problem:** Marty buys 3 pieces of yellow fabric, each 0.35 m long, and 5 pieces of green fabric, each 0.35 m long. We need to find the total length of fabric bought. 2. **Formula used:** To find the total length, multiply the number of pieces by the length of each piece and then add the lengths of all colors: $$\text{Total length} = (\text{number of yellow pieces} \times \text{length of each yellow piece}) + (\text{number of green pieces} \times \text{length of each green piece})$$ 3. **Apply the values:** $$= (3 \times 0.35) + (5 \times 0.35)$$ 4. **Calculate each part:** $$3 \times 0.35 = 1.05$$ $$5 \times 0.35 = 1.75$$ 5. **Add the results:** $$1.05 + 1.75 = 2.8$$ 6. **Conclusion:** Marty bought a total of **2.8 meters** of fabric.
