Answer:
Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16
Step-by-step explanation:
Let the number he gave to Alaina be x. Now, we know he gave twice as many to Miguel. Amount received by Miguel is 2x.
He gave Kira 2 times what he gave Miguel, that is 2x * 2 = 4x
Addition of all these equals 28. We now get x
4x + 2x + x = 28
7x = 28
X = 28/7
x = 4
Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16
