Answer:
Explanation:
First find total the weight of all red footed macaws whic is 525(2)=1050
and then the blue and gold macaws 800(3)= 2400
So add them both together yu get 3450grams or 3.45kg
So it is closer to 3kg because the total weight is under 3.5kg so that means you round down to 3kg. If it was 3.5kg you would round up to 4kg but their combined weight is not more than 3.45kg
