Two liquids,A and B,are mixed together.Liquid A has mass m and was initially at temperature 40 ^$\circ$ C,and liquid B has mass 2m and was initially at temperature 5 ^$\circ$ C.The specific heat of liquid A is 1.5 times that of liquid B. Calculate the final temperature of the mixture.

A) 33.5 ^$\circ$ C
B) 14.3 ^$\circ$ C
C) 17.0 ^$\circ$ C
D) 20.0 ^$\circ$ C
E) 25.7 ^$\circ$ C
