I think 700 because if b and c = 440 that means they both are 220 single and a c =520 as a whole so it’s 260

It may be 700 don’t take my word for it

Answer:

a = 290 kg

b = 210 kg

c = 230 kg

Step-by-step explanation:

a + b = 500

b + c = 440

b = 440 - c

a + c = 520

a = 520 - c

a + b = 500

440 - c + 520 - c = 500

460 = 2c

c = 230

a = 520 - 230

a = 290

b = 440 - 230

b = 210
