Answer: 948 grams
Explanation:
Kilograms of food purchased = 2.12 kilograms = 2120 grams
Number of grams of food pellets to the rabbits = 177
Number of grams given to the chickens = 276
Number of grams of pellets given to the ducks = 0.1kg = 100 grams
Number of grams given to the goats = 619
Then, grams of food pellets that Allison give to the calves will be:
= 2120 - (177 + 276 + 100 + 619)
= 2120 - 1172
= 948 grams
Therefore, the grams of food pellets that Allison give to the calves is 948 grams.
Note that 1000 grams = 1 kilogram
