Answer = 125 minutes

Assuming that the customers uses x minutes in a month.

The first plan can be represented as :

• 20+ 0.19x ....... equation 1 .

The second plan can be represented as :

• 25 +0.15x ....equation 2

When we equate both equation , we ca find the minutes of call of two plans :


20\text{ + 0.19x = }25\text{ +0.15 x }

Solving the above equation, we get that :


\begin{gathered} 0.19x\text{ -0.15x = 25 -20 } \\ \Rightarrow\text{ 0.04 x = 5 } \\ \therefore\text{ x = }(5)/(0.04) \\ \text{ = 125 minutes } \end{gathered}This means that, for 125 minutes , both option will be equal.
