Answer:


291.25 talk minutes would produce the same cost for both plans.
Step-by-step explanation:
Both plans can be modeled by a first order equation in the following format:

In which
is the initial cost, f is the fee that is paid for each minute, and t is the number of minutes.
Cost of the first plan:
The problem states that the first plan charges a rate of 24 cents per minute, which means that
.There is no initial cost, so
.
The equation for this plan is:

Cost of the second plan:
The problem states that the second plan charges a monthly fee of $34.95 plus 12 cents per minute. So
and 
The equation for this plan is:

Find the number of talk minutes that would produce the same cost for both plan:
This is the instant t in which:





291.25 talk minutes would produce the same cost for both plans.
