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.
