Question

You have the option of two phone plans. The Link One plan will charge you $0.50 for a phone call, plus $0.40 per minute. The Family plan will charge you $0.48 per minute. How much time would you need to spend on one phone call so that both plans would cost the same amount?

Answer 1

.50 + .40m  = .48m     where m is the number of minutes that equalize the cost......subtract .40m  from each side

 

.50  = .08m     divide both sides by .08

 

.50 /.08  = m   = 6.25 minutes
