3w + 8 - w = 4w - 2(w - 4)
is an identity
3w-w + 8 = 4w - 2w + 8
2w + 8 = 2w + 8
2w - 2w = 8 - 8
0 = 0
zero equal to zero implies that any value of w satisfies the statement 3w + 8 - w = 4w - 2(w - 4) hence it is an identity.

Answer:
$1,562.50
Step-by-step explanation:
Markup= (selling price- cost)/cost
Let cost be represented by C
0.20 = (1875-C)/ C
0.20C = 1875 - C
0.20C+ C = 1875
1.20C=1875
Divide both sides by 1.20;
C= 1875/1.20
C= $1,562.50
The wholesale cost was $1,562.50
1.99/32=0.06 an oz
3.69/64=0.05 an oz
5.85/96=0.06 an oz
therefore it is 64 oz
