Final answer:
To represent the amount paid A as a function, we use the equation A = k * P, where k represents the number of kilograms bought and P represents the cost per kilogram (P55.00).
Step-by-step explanation:
To represent the amount paid A as a function, we can use the equation A = k * P, where k represents the number of kilograms bought and P represents the cost per kilogram. In this case, the cost per kilogram is P55.00. So, the function becomes A = k * 55.00.
