Percentages involving Finances: Profit and Loss

A storeowner buys a certain number of goods from supplier A at \(\$6\) as a unit price and sell at \(\$12\) as a unit price. The storeowner bears all other costs at \(\$4,000\) in total. Suppose the owner manages to sell all the goods and earns a profit of \(20\%\) on the total cost.

1. Find the number of goods the owner buys from supplier A.

Another supplier B offers a lower unit price at \(\$4\) to the storeowner. The storeowner buys a new number of such goods from supplier B and sell at the unit price \(\$12\). But this time the storeowner only sells \(45\%\) of the goods and made a loss of \(10\%\) on the total cost. Suppose all other costs are also \(\$4,000\) in total.

2. Find the new number of goods the owner buys from supplier B.
