(A) $1,600 loss
(B) $600 loss
(C) No profit or loss
(D) $600 profit
(E) $1,600 profit

OA D

sold 800 units for $8 each so 800*8= $6400 (sale 1).
sold 1000 units for $5 each so 5*1000 = $5000 (sale 2)

cost of units sold in sale 1 = $6*800=$4800
cost of units sold in sale 2 = $6*1000=$6000

now all wehave to do is subtract things. taeaway the cost of each from its sale.

and you are left with a +$600 and thats your profit. so the answer is D.
