Hammers and wrenches are manufactured at a uniform weight per hammer and a uniform weight per wrench. If the total weight of two hammers and three wrenches is one-third that of 6 hammers and 5 wrenches, then the total weight of one wrench is how many times that of one hammer?	Select:	A) 1/4	B) 2/3	C) 1	D) 3/2	E) 2
x be the weight of a hammer and y be the weight of a wrench.   (2x+3y)=1/3*(7x+5y)   3(2x+3y)=(7x+5y)   6x+9y=7x+5y   4y=x   y=x/4   1/4ns - 1/4
