Ответ:
Kelly got 3^3 (27) while Alia got 4^2 (16) less than her. When you put it together you get 3^3 - 4^2
Ответ:
Option D. Alia gets 3³ - 4² = 11 jelly beans.
Step-by-step explanation:
Kathy gives Kelly 3³ jelly beans.
Kathy gives Alia 4² fewer jelly beans than Kelly. This means that Alia gets the number of jelly beans obtained by Kelly decreased by 4².
To summarize:
#Kelly = 3³ = 27
#Alia = #Kelly - 4² = 3³ - 4² = 27 - 16 = 11
Then, option D is correct.
