The concession at VHS sells hot chocolate and coffee at the high school football games. At the last game, they had sales of $200.
They need to keep track of how many of each type drink was sold
so that they can make predictions for future sales. Monica knows
that they used 275 cups that night. If the hot chocolate sells for 75
cents and coffee sells for 50 cents, how much of each type of drink
were sold?

Data for the height of a model rocket launch in the air over time are shown in the table. darryl predicted that the height of the rocket at 8 seconds would be about 93 meters. did darryl make a good prediction? yes, the data are best modeled by a quadratic function. the value of the function at 8 seconds is about 93 meters. yes, the data are best modeled by a linear function. the first differences are constant, so about 93 meters at 8 seconds is reasonable. no, the data are exponential. a better prediction is 150 meters. no, the data are best modeled by a cubic function. a better prediction is 100 meters.
