specific heat capacity

A nursing mother prepared her baby’s milk mixture at 85 degree Celsius in a feeding bottle. In order to cool it to 40 degree Celsius, she then immersed it in an aluminum bowl of heat capacity 90J/ K containing 500g of water at 26 degree Celsius. If the mass of the mixture is 300g, calculate the specific heat capacity of the mixture? { neglect heat losses and heat capacity of the bottle; specific heat capacity of water 4200JKgK}
