- Q8
A supermarket offers two pricing models for purchasing fruits:

Model B: ₱40 per kilogram for any amount purchased.
For a customer who buys 5 kilograms of fruit, which model is more cost-effective and why?
Model B, because it offers a flat rate.
Model A, because it has a lower cost per kilogram for more than 1 kilogram.
Model A, because it costs ₱90 for 5 kilograms.
Model B, because it costs ₱200 for 5 kilograms.
