Question

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of

airtime usage. If Juanita uses x minutes of airtime, what is an equation that can be
used to determine her monthly cell phone bill (C)?
C = 15 + 0.20%
C =15 (0.20%)
C# 15 + X+ 0.20
C = 0.20 + 15x

Answer 1

It wouldn’t be any of these I don’t think, however I don’t know what the # means.

I thought it would be C = 15 + x(0.20)

Hope this helps
