Sagot :

Answer:

Step-by-step explanation:

Let X be the total number of minutes.

the 1st 3 minutes of your call is Php 8, this is a constant value.

the the charge for remaining minutes after the 3minutes count can be written as

3 ( X - 3 )

therefore, Y (total charge)

Y = 8 + 3 (X - 3)

simplifying the equation

Y = 8 + 3X - 9

Y = 3X - 1

the answer is B.
