Plan A $17 plus 0.10 for each min of calls. Plan B &13 plus an additional 0.15 for each min. What amount do the two plans cost the same?

80 minutes ; $25

Step-by-step explanation:

Let x = number of minutes

Plan A :

17 + 0.1x - - - (1)

PLAN B :

13 + 0.15x - - - (2)

Both plans will cost the same when ;

17 + 0.1x = 13 + 0.15x

Solve for X

0.1x - 0.15x = 13 - 17

-0.05x = - 4

divide both sides by - 0.05

-0.05x / - 0.05 = - 4 / - 0.05

x = 80 minutes

Amount :

17 + 0.1(80) = 17 + 8 = $25
