Answer:
7 cards
Step-by-step explanation:
Well if John started off with 28 and gave away 10,
28-10=18
Gave tthe last 18 to his brother
18-18 = 0
Gained 10
0+10=10
Lost 3
10-3=7
Hence, John has 7 cards left.
He has 7 cards left since,
He had 28
gave away 10 so, 28 - 10 = 18
he was left with 18 and gave the rest which is (18) to his brother
Now he has 0
but then he gained 10
he lost 3 so 10 - 3 = 7
So, he has 7 cards now
Hope this helps!!
