Final answer:
The function y=50-3.5x is a continuous function that represents the amount of money left after buying x loaves of bread.
Step-by-step explanation:
The function y=50-3.5x represents the amount of money in dollars that you have left after buying x loaves of bread. This function is a continuous function.
A continuous function is a function that can take on any value within a given interval. In this case, the x-values represent the number of loaves of bread purchased, which can be any positive real number. The y-values represent the amount of money left after buying those loaves of bread, which can also be any positive real number.
For example, if you buy 1 loaf of bread (x=1), the function gives y=46.5. If you buy 2 loaves of bread (x=2), the function gives y=43. If you buy half a loaf of bread (x=0.5), the function gives y=48.25.
