Hello!
The answer is:
Darwin earned 4050 pesos
Why?
To solve the problem, first, we need to calculate the total quantity of corned beef, and then, calculate the total earning amount.
We have a box of corned beef one and half dozen cans, or 1.5 zones.
So, calculating we have:
![TotalBeef=Dozen*1.5=12*1.5=18](https://img.qammunity.org/2020/formulas/mathematics/middle-school/q28pvuc9khgybjnlgvd5xafinbkmmy7223.png)
We have that there are 18 cans of corned beef per box, now, if he sold all the 5 boxes of corned in 45.00 pesos each, we have:
![TotalEarning=Cans*45.00(pesos)=18*5*45.00pesos=4050(pesos)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/offyzqhhb5jmxnm7r808vm3q6tfv5ria9q.png)
Hence, we have that Darwin earned 4050 pesos.
Have a nice day!
