Given the cost of phone calls per 30 seconds = 55k
What is the rate per minute?
Solution:
1 minute = 60 seconds
Since it cost 55k in 30 seconds, multiplying the cost by 2 will give the rate per minute since half of 1 minute or 60 seconds is 30 seconds.
= (55k)(2)
= 110k
The rate per minute is 110k.
