Answer :
Given : Mihika makes 8 gift packs , Where in each one of them she put 12 vanilla chocolates , 14 milk chocolates and 8 nut chocolate .
So ,
In one pack she pack total chocolates == ( 12 + 14 + 8 )
So ,
In 8 gift pack total number of chocolates = 8 ( 12 + 14 + 8 )
Now we apply distributive property and get
8 ( 12 + 14 + 8 ) = 8 12 + 8 14 + 8 8 = 96 + 112 + 64 = 272
So,
She packs total numbers of chocolates in 8 packs = 272 ( Ans )
