Final answer:
Lina's total payment for meat and chicken is calculated by adding the product of the weight and price of each item separately, resulting in the answer C) p * RMx + q * RMy.
Step-by-step explanation:
The question Lina bought p kg of meat at RMx a kg and q kg of chicken at RMy per kg. How much money does Lina have to pay? pertains to math operations involving multiplication and addition when calculating total cost. To determine the total amount of money Lina has to pay for the meat and chicken, we apply the sum of the products of each item's weight and price separately:
- Cost of meat = p * RMx
- Cost of chicken = q * RMy
Adding these together gives us the total amount Lina has to pay:
Total cost = p * RMx + q * RMy
Therefore, the correct answer to the question is option C) p * RMx + q * RMy.
