Charlie owns one flute, two horns, and a harp.  Carli owns twice as many flutes as Charlie, half as many horns as Charlie, but no harps.  What is the combined total number of musical instruments owned by Charlie and Carli?
Charlie owns one flute, two horns, and a harp for a total of 1+2+1=<<1+2+1=4>>4 instruments.
Twice as many flutes as Charlie is 2*1=<<2*1=2>>2 flutes,
Half as many horns as Charlie is 2/2=<<2/2=1>>1 horn
Thus, Carli owns 2+1=<<2+1=3>>3 instruments.
Therefore, the combined total number of musical instruments owned by Charlie and Carli is 4+3=<<4+3=7>>7 instruments.
