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?
A. (B + 200)/2
B. (B + 2)/6
C. (2B + 200)/3
D. (B + 2)/3
E. (B - 2)/6
The OA is B.
I get the solution as follow,
Let paint price = P, and whitewash price = W.
P + W = B
It's given that P = 2W - 200/100
Substituting the value of P
2W - 2 +W = B
W = (B + 2)/3
So, half price = (B + 2)/6. Option B.
Experts, any suggestion? Thanks!
