Answer

150 channels: 0.20/channel 210 channels: 0.17/channel 225 channels: 0.18/channel

Work Step by Step

150 channels $\frac{29.99}{150\>channels}$ = $\frac{29.99\div150}{150\div150\>channels}$ = $\frac{0.20}{1\>channel}$ = 0.20/channel 210 channels $\frac{34.99}{210\>channels}$ = $\frac{34.99\div210}{210\div210\>channels}$ = $\frac{0.17}{1\>channel}$ = 0.17/channel 225 channels $\frac{39.99}{225\>channels}$ = $\frac{39.99\div225}{225\div225\>channels}$ = $\frac{0.18}{1\>channel}$ = 0.18/channel
