Answer:
C (10×4) ÷ 2
Step-by-step explanation:
C is the answer because if you do an equation,
10 multiplied by 4 (10×4)
Then, she wants to share the dolls equally for her brother
This means that you have to multi[ly 4 by 10, so you get 40. If she shares the dolls equally with her brother, she will give him 20 and keep 20 for herself.
C provides the correct answer with 20. 40/2 is 20
