Your question asks what would be the cost of the sales that Zhang Industries made at the end of June 30th.
In order to solve your question, lets gather some important information.
Important Information:
With the information above, we can find the answer.
We know that each month's sales increase by 3%. This means that from May to June, the amount of sales increased by 3%, so we need to find how much they made in June.
We would find this by multiplying 400 by 1.03
[tex]400*1.03=412[/tex]
In June, they sold 412 products.
We know that each product was sold for $700 each, so we would multiply 412 by 700 in order to get the amount they made from sales.
[tex]412*700=288,400[/tex]
When you're done solving, you should get 288,400.
This means that the total sales they made from the product at the end of June 30th is $288,400.
