Answer:
[tex]\large\boxed{\$400}[/tex]
Step-by-step explanation:
In this question, we're trying to find how much each bull cost.
We know that:
With the information above, we can solve the question.
To find how much the farmer made from the cows, we would multiply 20 by 300
[tex]20*300=6000[/tex]
The farmer made $6,000 from the cows.
We know that the farmer used all the money to buy 15 bulls.
We would divide 6000 by 15 to find the cost for each bull.
[tex]6000\div15=400[/tex]
When you divide, you should get 400.
This means that each bull cost $400 each.
