Can someone please take the time to explain this problem in easy to understand language step by step.

Two genetically engineered enzymes are produced simultaneously from a series of chemical and biological processes: Q enzyme and Y enzyme. The cost per batch of Q and Y enzymes is $200,000, resulting in 300 grams of Q and 200 grams of Y. Before Q and Y can be sold, they must be processed further at costs of $100 and $150 per gram, respectively. Each batch requires one month of processing time and only one batch per month is produced.

The monthly demand for Q and Y depends on the price charged. The following table summarizes the various price-quantity combinations.

Quantity Sold	Price per Gram of Q	Price per Gram of Y
50	$1,200	$750
100	1,100	550
150	1,000	350
200	900	150
250	800	n.a.
300	700	n.a.

In the following analysis, the optimum price of Q is $900 per gram and the optimum price of Y is $750 per gram.

Quantity Sold	Price per Q	Revenue of Q	Total Cost of Q*	Total Profit	Price per Y	Revenue from Y	Total cost of Y	Total Profit
50	$1,200	$ 60,000	$ 25,000	$35,000	$750	$37,500	$ 27,500	$10,000
100	1,100	110,000	50,000	60,000	550	55,000	55,000	0
150	1,000	150,000	75,000	75,000	350	52,500	82,500	(30,000)
200	900	180,000	100,000	80,000	150	30,000	110,000	(80,000)
250	800	200,000	125,000	75,000	n.a.
300	700	210,000	150,000	60,000	n.a.

a.	Critically evaluate the analysis underlying the pricing decisions of $900 for Q and $750 for Y.
b.	What should management do if the cost per batch rises to $225,000?
