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?
Thoughts? Step-by-step reasoning:
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.
Thus, the answer is 48000.
