Answer:
none of the above
Step-by-step explanation:
A <em>Hamilton path</em> is one that visits each node exactly once. In a graph with 6 nodes, the path length must be exactly 6.
Only one answer choice is of length 6: ADEFBC. However, it includes travel from F to B, which path does not exist in the graph shown. Hence the only viable choice is not an answer.

Let M = #miles driven
Plan 1: .50M + 70 = total cost
Plan 2 .70M = total cost
To know how far she would drive to have an equal cost for either plan just set the equations equal to each other
.70M = .50M + 70
subtract .50M from both sides
.20M = 70
M = 70/.20 = 350 miles
Check the answser:
Plan 1: .50(350) + 70 = 175 + 70 = $245
Plan 2: .7(350) = $245
they are equal so our answer checks as correct
New volume of mixture
= 30%/20%*30 oz
= 45 oz
Jalen must therefore add (45-30)=15 oz of water.
