A telephone company advertises long distance service for $0.15 per minute plus a monthly fee of $5.50. If your bill one month was $40, find the number of minutes you used making long distance calls. Which equation represents the monthly bill? O y = 5.50x+0.15 O y = 5.50x -0.15 O y = 0.15x -5.50 O y = 0.15x + 5.50
