I'll try to explain in the simplest way possible:
Total cost for a single widget: $32 + $44 = $76 for one widget.
So, since we know the cost of one widget is $76, then the price of 350 widgets would be = $76 x 350 = $26,600.
total mass = mass of a bag of candy + mass of a chocolate bar
total mass = 80g +110g = 190g
The answer for this question would be 2 I think
