Answer:

Calving earning = 4400

Betty earning = 9400

Albert earning = 4700

Donna = 8800

Step-by-step explanation:

Given that :

Calving earning = c

Betty earning = c + 5000

Albert earning = (c + 5000) /2

Donna = 2c

c + 5000 + (c + 5000) /2 = 900 + c + 2c

c + 5000 + 0.5c + 2500 = 900 + 3c

1.5c + 7500 = 900 + 3c

7500 - 900 = 3c - 1.5c

6600 = 1.5c

c = 6600 / 1.5

c = 4400

Calving earning = c = 4400

Betty earning = 4400 + 5000 = 9400

Albert earning = (4400 + 5000) /2 = 4700

Donna = 2(4400) = 8800
