Answer
Each Reese's has 232 calories and each Snickers bar has 273 calories
Work Step by Step
s = calories in a Snickers bar
y = calories in each Reese's
s + 2r = 737
2s + r = 778
s + 2r = 737 can be written as s = 737 - 2r. Plug this into 2s + r = 778
2(737 - 2r) + r = 778
1474 - 4r + r = 778
1474 - 3r = 778
696 = 3r
r = 232
Each Reese's has 232 calories
Plug r into s + 2r = 737
s + 2(232) = 737
s = 273
Each Snickers bar has 273 calories
