1. **State the problem:** Rema buys 140 plants with different costs based on percentages and fractions. We need to find the total cost. 2. **Identify quantities:** - 35% of 140 plants cost 6 each. - \frac{1}{4} of 140 plants cost 8 each. - The rest cost 10 each. 3. **Calculate number of plants in each group:** - Plants costing 6: $0.35 \times 140 = 49$ - Plants costing 8: $\frac{1}{4} \times 140 = 35$ - Plants costing 10: $140 - (49 + 35) = 140 - 84 = 56$ 4. **Calculate total cost for each group:** - Cost for 6 each: $49 \times 6 = 294$ - Cost for 8 each: $35 \times 8 = 280$ - Cost for 10 each: $56 \times 10 = 560$ 5. **Calculate total cost:** $$294 + 280 + 560 = 1134$$ **Final answer:** The total cost of the 140 plants is 1134.
