Answer:
d. 2.45 QAR.
Step-by-step explanation:
To calculate the cost of purchasing 0.7kg of cucumbers at a rate of 3.50 QAR per kilogram, we can use the formula:
Cost = Rate × Quantity
Here's how to calculate it:
1. Multiply the rate per kilogram (3.50 QAR) by the quantity (0.7kg):
- Cost = 3.50 QAR/kg × 0.7kg
2. Calculate the result:
- Cost = 2.45 QAR
Therefore, the cost of purchasing 0.7kg of cucumbers at a rate of 3.50 QAR per kilogram is 2.45 QAR.
