Answer 1

The rate of On call is cost divided by time

Since the cost is 10 dollars and the time is 2.5 hours, then

The rate = 10/2.5 = 4 dollars per hour

The rat of ON-Call is 4 dollars per hour

The cost of 3/4 hour is 1.75 dollars in the Talk Time, then

The rate = 1.75/(3/4) = 7/3 = 2 1/3 = 2.3333 dollars per hour

The rate of Talk-Time is 2.3333 dollars per hour

Since the rate of talk-time rate is lower than the On-call rate

Then the talk-time is the better offer
