Sorry, I am a little rust on expressions so this may not be exactly what your instructor is looking for (so make it work for you):
26a: Samantha = S
S = -10 + (-10) + 3 (king of hearts = (-10); jack of diamonds = (-10); and 3 of spades = +3.
S= -17
26b: Warren = W
W = 7+2+(-7) (7 of clubs = 7; 2 of spades = 2; 7 of hearts = (-7)
W = 2
26c. Warren won 2>(-17)
26d. 3 of spades, jack of spades and 6 of hearts (3+10-6=7) and 1 of spades, 2 of spades, 4 of spades (1+2+4-7)
