Question

A wireless phone plan costs eric $35 for a month of service during which he sent 450 text messages.if he was charged a fixed fee of 12.50,how much did he pay per text

Answer 1

Answer: Eric paid $0.05 or 5 cents per text.

We have

Cost of wireless phone plan $35

Fixed charges $12.50

Cost of the text messages
`22.50 (35 -12.50)`

We need to deduct the Fixed charges, because Eric would have had to pay those charges even if he didn't send one text messages.

So, the cost per text messages is
`(22.50)/(450) = 0.05`
