Respuesta :

PART A:

Based on the given information, if w is the number of walks the cost of plan1 and plan2 can modeled as follow:

Plan1 cost:

10 + 3w

Plan2 cost:

5w

The equation wich allows one to determine the number of walks w at which the cost for both plans is the same is:

10 + 3w = 5w

PART B:

Solve the equation for partA as follow:

10 + 3w = 5w subtract 3w both sides and simplify

10 = 5w - 3w

10 = 2w divide by 2 both sides

10/2 = w

5 = w

w = 5

Hence, you can conclude that for 5 walks the cost of both plans A and B is the same.
