Cell phone Company A charges a one-time activation fee of $23.75, plus an additional monthly fee of $24.25, plus $0.05 per minute for calls. Cell phone Company B charges a monthly fee of $29, plus $0.10 per minute for calls. After how many minutes of calls would the cost for each company be the same for the first month?A.) 300 minutesB.) 320 minutesC.) 360 minutesD.) 380 minutes

Answer»

Company A COSTS total 23.75+24.25 = 48 and company B = 29

Difference in their fees is $ 19

For each minute company B calls cost 0.10$ and company A costs 0.05$
which means for each minute company B costs 0.05$ more.

So, we NEED NUMBER of minutes after which they cost the same i.e., difference in costs should become 0$

Hence,
No. of minutes = Diff in fees/ cost difference per minute

= 19$/0.05$
= 19*100/5
= 380 minutes
