The minimum cost for this spanning tree has been calculated as $1100.
This is solves as
AC + CD + DF + FE + EB
This would be
15 + 25+ 23 + 22 + 25
= 110
The minimum cost would be gotten by multiplying this valus with the amount per foot
= 10 * 110
= $1100
Hence the minimum cost of the spanning tree is $1100
