Answer:
1) 68+28 = 96 cards
2) 278.32 - 3698 is a question that gives a negative answer
We rewrite as;
278.32
- 3698,00 = see 78.32 - 98.00 turns to -19.68 and 200 - 3600 = -3400
- 3400 -+19.68 = - 3419.68
We add the last bit as it is the remainder of 3400 if done separately.
2b) With adding both numbers 278..32 + 3698 = 3976.32
-3(x - 10) > = -3 <== ur inequality
-3x + 30 > = -3
-3x > = -3 - 30
-3x > = -33
x < = -33/-3
x < = 11 <== ur solution
The answer to your question is 20
