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. $41.10$
