Answer:
Amount of sodium in a hot dog = 860 mg.
Amount of sodium in a cup of cottage cheese = 1000 mg.
Step-by-step explanation:
Let the amount of sodium in a hot dog be x mg and the amount in a cup of cottage cheese be y mg.
2x + 3y = 4720
5x + 2y = 6300
Multiply the first equation by 2 and the second by 3. We get:
4x + 6y = 9440 (a)
15x + 6y = 18900 (b)
Subtract: (b) - (a):
11x = 9460
x = 9460 / 11 = 860 mg.
To find we we substitute x = 860 in the first original equation:
2(860) + 3y = 4720
3y = 3000
y = 1000 mg.
