To arrive at the smallest value of d we need to determine the cost of per bowl, and we are told that it is an integer, that means it should be divisible.
Total bowls can be made = 6 X v X b => 6vb.
Cost per pound = d/6,
Cost per bowl = d/6vb. choosing 2 as v and 3 as b, = d/6*2*3 => d/36.
Since d/36 is an integer, we can see that d is 36 when small to get $1 as each bowl's cost.
