Solve the problem.If a parking ramp attendant can wait on 5 vehicles per minute, and vehicles are leaving the ramp at x vehicles per minute, then the average wait in minutes for a car trying to exit is given by 
Solve the inequality 
to determine the exit rates x that would result in average wait times between 4 and 9 minutes.
A. 4.8 ? x ? 4.9 B. 4.7 ? x ? 5.0 C. 0.7 ? x ? 1.5 D. x ? 4.9 or x ? 4.8
Factor out the polynomial GCF.t(3 - m) + s(3 - m)
A. (t - s)(3 - m) B. t(3 - m) + s C. no common factor D. (t + s)(3 - m)
Interpret the linear equation.The monthly cost of a certain long distance service is given by the linear function 
where y is in dollars and x is the amount of time in minutes called in a month. Find and interpret the slope and y-intercept of the linear equation.
A. m = 0.08; The number of minutes called in a month increases 0.08 for every dollar spent. b = 7.95; The number of minutes that can be called when x = 0 is 7.95. B. m = 7.95; The number of minutes called in a month increases 7.95 for every dollar spent. b = 0.08; The number of minutes that can be called when x = 0 is 0.08. C. m = 7.95; The cost of the long distance service increases $7.95 for every 1 minute called. b = 0.08; The cost of the long distance service is $0.08 if no calls are made for the month. D. m = 0.08; The cost of the long distance service increases $0.08 for every 1 minute called. b = 7.95; The cost of the long distance service is $7.95 if no calls are made for the month.
