Answer 2

Solution:(a) The value of samantha cards is -17. (b) The value of Warren cards is 2. (c) The winner name is Warren. (d) First way is king of Diamond , queen of club , 7 of spade and Second way is queen of heart, 8 of club, 9 of spade.

Step-by-step explanation:

(a) It is given that red cards are negative and black cards are positive. Points of face card is 10.

Samanth has a king heart which is a red face card so the value of this card is negative 10. Jack of diamond is a red face card so the value of this card is negative 10. The value of 3 of spade is positive 3.

`-10-10+3=-17`

Therefore, the value of Samanth's cards is -17.

(b)Warren has 7 of club which is a black card so the value of this card is positive 7. The value of 2 of spade is positive 2 and the value of 7 of heart is negative -7.

`7+2-7=2`

Therefore, the value of Warren's cards is 2.

(c) The winner name is Warren.

From part (a) and (b) it is noticed that the value of Samanth's cards is -17 and the value of Warren's cards is 2.

Since 2>-17 therefore warren is the winner.

(d)The first way to score 7 is king of Diamond , queen of club , 7 of spade.

`-10+10+7=7`

The second way to score 7 is queen of heart, 8 of club, 9 of spade.

`-10+8+9=7`

Therefore, Two ways are king of Diamond , queen of club , 7 of spade and queen of heart, 8 of club, 9 of spade.
