Stumped by Wording

CNJNLUV · #1 Feb 29, 2008, 01:03 PM

I have problems dealing with word problems and I hope I can get some help in going in the right direction.

A telephone bill lists a minimum of $7.50 for first 80 message units. What is the additional cost if it's plus 0.06 per unit for the next 60 units, plus 0.05 per unit for the next 60 units, and plus 0.04 per unit for any units beyond 200.

Thanks.
