A customer asks the clerk for a paintbrush and a bucket of whitewash for a total price of B dollars. If the paintbrush costs 200 cents less than twice the price of a bucket of whitewash, what is the price of half a bucket of whitewash in dollars?
.  Choose the most appropriate option:
A) (B + 200)/2.
B) (B + 2)/6.
C) (2B + 200)/3.
D) (B + 2)/3.
E) (B - 2)/6
P: cost of 1 paint brush in cents; W: cost of 1 bucket of white wash in cents   P + W = 100*B cents (B dollars)   paintbrush costs 200 cents less than twice the price of a bucket of whitewash   So, P-200 = 2W ---&gt; P=2W+200   P + W = 100*B cents (B dollars) ---&gt; 2W+200+W = 100*B ---&gt; 3W = 100*B - 200 ---&gt; W = (100B - 200)/3   Price of half bucket of White wash = W/2 = (100B - 200)/6 dollars or (B-2)/6 in cents.   Answer is (B - 2)/6.
