Answer:
Trudy made 48 biscuits.
Step-by-step explanation:
To find the number of biscuits Trudy made, we can use the comparison method:
Part Biscuits
Trudy : (Trudy + Bella) = Trudy : (Trudy + Bella)
3 : (3 + 2) = Trudy : 80 biscuits
3 : 5 = Trudy : 80 biscuits
5 × Trudy = 3 × 80 biscuits
Trudy = (240 ÷ 5) biscuits
= 48 biscuits
