The maximum weight of pineapple that can be put in the mix is 7.69 kg. This is because the effective wholesale cost of the mix must be no greater than $2.00 per kg, and the wholesale price of pineapple is $2.50 per kg. Therefore, the maximum weight of pineapple that can be put in the mix is 10 kg - 7.69 kg = 2.31 kg.
