Phone Company A charges a monthly fee of $41.10, and $0.02 for each minute of talk time
A = (x)(0.02) + 41.10
Phone Company B charges a monthly fee of $25.00, and $0.09 for each minute of talk time
B = (x)(0.09) + 25.00
When A = B, then,
(x)(0.02) + 41.10 = (x)(0.09) + 25.00
16.10 = .07x
x = 230 minutes
