Question

Create a linear equation to represent the monthly bill. When will the plans cost the same? Explain which plan is a better option.Plan A $25.75 plus $.75 per min Plan B $20.99 plus 1.00 per min

Answer 1

The first answer is wrong.

Explanation:

.75x+25.99=x+20.99

-20.99 -20.99

.75x+5.00=x

-.75x -.75x

5=.25x

x=20

Answer 2

Let x be the number of minutes used. The first plan's equation would be 25.75 + 0.75x and the second plan's equation would be 20.99 + x. To find when the plans would be the same, we can set these two equations equal to each other.

25.75 + 0.75x = 20.99 + x

4.76 = 0.25x

19.04 = x

This means that the plans will be even if the number of minutes used is 19.04.
