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?
Regina has 4 pigs/cow * 20 cows = <T>multiply(4, 20)=80 pigs.
She could sell the pigs for 80 pigs * $400/pig = $<T>multiply(80, 400)=32000
For the cows Regina would get 20 cows * $800/cow = $<T>multiply(20, 800)=16000
In total Regina would earn $16000 + $32000 = $<T>add(16000, 32000)=48000
