Question

My friend and I have different calling plans. Mine has a monthly fee of $10 and $0.08 per minute charge. My friend pays $0.06 a minute and a $15 monthly customer fee.
After how many minutes will our plans cost the same amount? Round your answer to the nearest minute.

Answer 1

difference is monthly customer fee= 15-10 = $5

difference in minutely charge = 0.08-0.06 = $0.02

minutes it takes for plans to cost same amount= 5÷0.02 = 250 min
