I just need help with C, the bolded question at the end. Thank you!

The Donald Fertilizer Company produces industrial chemical fertilizers. The projected manufacturing requirements (in gallons) for the next four quarters are 90,000, 90,000, 60,000, and 140,000 respectively. A level workforce is desired, relying only on anticipation inventory as a supply option. Stockouts and backorders are to be avoided, as are overtime and undertime.

a. Determine the quarterly production rate required to meet total demand for the year, and minimize the anticipation inventory that would be left over at the end of the year. Beginning inventory is 0.

The quarterly production rate is=95000 gallons. (Enter your response as an integer.)

b. Specify the anticipation inventory that will be produced. (Enter your responses as an integers.)

Quarter	1	2	3	4
Anticipation inventory (gallons)	5000	10000	45000	0

c. Suppose that the requirements (in gallons) for the next four quarters are revised to 140,000, 60,000, 90,000, and 90,000 respectively. If total demand is the same, what level of production rate is needed now, using the same strategy as above?
