Regina has a farm with animals. She has 20 cows and four times more pigs. Someone told her, that she could sell all the animals and earn $400 for each pig and $800 for each cow. How much money would she earn if she would sell all the animals from the farm?
Stream of thoughts:
48000
Regina has 4 pigs / cow * 20 cows = 80 pigs.

She could sell the pigs for 80 pigs * $400 / pig = $32000.

For the cows Regina would get 20 cows * $800 / cow = $16000.

In total Regina would earn $16000 + $32000 = $48000.

The answer: 48000
