Explanation

(a)(i) Profit-maximizing output level is 900 because at this output level MC = MR

(ii) TR =$10x600 -$6,000
     TC = $6 x 600 = $3,600
     Profit = TR -TC -S 2, 400
(iii)TC =ATC xQ
     $10 x 400 = $4,000
(b)(i) TR =P x Q = $10 x 900 = $9,000

(ii) At 900 units TR -TC 
     TC = $8 x 900 = $7,200
      Profit =$1800
(c) At any time price (AR) is below the average variable cost, TR will be less than TVC and operating profit will be negative, that is, there will be loss on operation. The firm will eventually close down.
