A certain office supply store stocks 2 sizes of self-stick notepads, each in 8 colors. The store packs the notepads in packages that contain either 3 notepads of the same size and the same color or 3 notepads of the same size and of 3 different colors. If the order in which the colors are packed is not considered, how many different packages of the types described above are possible?
Choose the correct choice from the following choices:
A) 6
B) 8
C) 16
D) 124
E) 128
Notepads of the same color = 8 (we have 8 colors). As we have two sizes then total for the same color=8*2=

<output>16</output>
16   Notepads of the different colors= 8C3=56 (we should choose 3 different colors out of 8). As we have two sizes then total for the different color=56*2= 
<gadget id="calculator">56*2</gadget>
<output>112</output>
112   Total=112+16= 
<gadget id="calculator">112+16</gadget>
<output>128</output>
