Find the additional minutes by subtracting the first three minutes from the total minutes consumed by the caller.
Find the total amount that the caller has to pay by adding the cost of the first three minutes to the product of the additional minutes and cost per additional minute.
Given:
cost of the first three minutes - Php 5
cost per additional minute - Php 1
total minutes consumed by the caller - 8
Solution:
Step 1: Subtract the first three minutes from the total minutes consumed by the caller.
8 mins - 3 mins = 5 mins
Step 2: Add the cost of the first three minutes to the product of the additional minutes and cost per additional minute.
Php 5 + (5 × Php 1)
= Php 5 + Php 5
= Php 10
Final Answer:
Php 10
