Answer:
95.91 g
Step-by-step explanation:
First we convert the given masses of grain and hay into grams:
- 0.75 lb of grain * 454 g/lb = 340.5 g of grain
- 4.25 lb of hay * 454 g/lb = 1929.5 g of hay
Now we calculate how many grams of protein Trixie consumes from grain:
- 340.5 g of grain * 14/100 = 47.67 g protein
And do the same for hay:
- 1929.5 g of hay * 2.5/100 = 48.24 g protein
Finally we add the protein grams:
