perfectely competitive market - 經濟

學校:American school

教師:John

科目:micro economic

題目:In a perfectly competitive market, a typical firm's total costs are
given by TC=8+4Q+Q平方, where marginal cost is MC=4+2Q. There are 10 such
firms, and they face a market demand of P=100-Q,

what is the firm's fixed cost? Average variable cost and average total cost?

Find the market supply curve and equilbrium price and quantity

How much profit will each firm earn?

我的想法:
跨組修課 有些基本原理有點不太理解
看了教科書也沒有怎麼提到在完全競爭市場中的FC 請教各位該怎麼算
接下來的子題例如AVC和ATC需要除以10 firms嗎?
整題有些不太理解
希望有人可以幫我釐清一下

謝謝
