At a certain restaurant, 10 sandwiches and 5 burritos will cost $65.50. In addition, 7 sandwiches and 8 burritos cost $77.80. Assuming that we are talking about the same sandwiches and burritos, what is the
cost of 1 sandwich? What is the cost of 1 burrito? Let x represent the cost of a sandwich and y represent
the cost of a burrito.
Equation #1:
Equation #2:
Cost of 1 sandwich:
Cost of 1 burrito:

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.
