Final answer:
The question cannot be answered accurately with the given information as the relationship between temperature and frozen fruit bar sales is not provided.
Step-by-step explanation:
The student's question involves finding the value of y (frozen fruit bars) when x (temperature in °F) is 80. Unfortunately, there is insufficient data provided to determine an exact answer as the necessary relationship (linear or otherwise) between the temperature and the number of frozen fruit bars sold has not been provided. To predict the value of y for x = 80°F accurately, we would need a complete dataset or a given formula that establishes the correlation between these two variables. In context, we would be likely looking for a linear regression to predict y based on x.
