1. **State the problem:** We are given the prices per kilo of different fruits and vegetables and asked various questions involving addition and subtraction of decimals. 2. **List prices:** Watermelon = 70.25 Cucumber = 64.75 Carrot = 95.50 Eggplant = 93.75 Banana = 105.85 3. **Question 2:** How much would it cost to buy 1 kilo each of eggplant, carrot, and watermelon? Calculate the sum: $$93.75 + 95.50 + 70.25 = 259.50$$ So, the total cost is $259.50$. 4. **Question 3:** Which two items cost 176.10 together? Check pairs: Watermelon + Cucumber = $70.25 + 64.75 = 135.00$ Watermelon + Carrot = $70.25 + 95.50 = 165.75$ Cucumber + Carrot = $64.75 + 95.50 = 160.25$ Eggplant + Watermelon = $93.75 + 70.25 = 164.00$ Carrot + Eggplant = $95.50 + 93.75 = 189.25$ Banana + Cucumber = $105.85 + 64.75 = 170.60$ Watermelon + Banana = $70.25 + 105.85 = 176.10$ This matches exactly. So, Watermelon and Banana cost $176.10$ together. 5. **Question 4:** Leo has 135.00, which two items can he buy one kilo each? Check pairs with sum ≤135.00: Watermelon + Cucumber = 135.00 (fits exactly) No other pair sums to ≤135.00. So, Leo can buy Watermelon and Cucumber. 6. **Question 5:** How much more expensive is a kilo of carrot than cucumber? Calculate difference: $$95.50 - 64.75 = 30.75$$ A kilo of carrot is $30.75$ more expensive. 7. **Question 6:** Which two items have a difference of 5.50 in price per kilo? Check differences: Watermelon - Cucumber = $70.25 - 64.75 = 5.50$ Others do not match 5.50. So, Watermelon and Cucumber differ by $5.50$. 8. **Question 7:** If you get one kilo each of Watermelon and Cucumber, total cost: $$70.25 + 64.75 = 135.00$$ 9. **Question 8:** Difference between most expensive and least expensive item: Most expensive = Banana = 105.85 Least expensive = Cucumber = 64.75 Difference: $$105.85 - 64.75 = 41.10$$ **Final answers:** 2. $259.50$ 3. Watermelon and Banana 4. Watermelon and Cucumber 5. $30.75$ 6. Watermelon and Cucumber 7. $135.00$ 8. $41.10$
