Final answer:
To find the total score of Jesse's hand, the values of the cards (4, -8, 9, and -7) are added together sequentially, resulting in a final score of -2.
Step-by-step explanation:
Jesse and Mark are playing the integer card game, and we want to find the total score of Jesse’s hand. The cards in Jesse's hand are 4, -8, 9, and -7. To find Jesse's total score, we add up the values of all the cards in his hand:
- Start with the first card: 4
- Add the second card: 4 + (-8) = -4
- Add the third card: -4 + 9 = 5
- Add the fourth card: 5 + (-7) = -2
Therefore, the total score for Jesse's hand is -2.
