Question

Gordon buys a loaf of bread 65 centimeters long. For lunch every afternoon, he cuts 15 centimeters of bread for his sandwich. Gordon wants to determine the length of the loaf of bread, l, after d days. What is the equation of the scenario? Is the graph of the equation continuous or discrete?

I need an answer asap pls!


a

l = 65 – 15d; continuous

b

l = 65 – 15d; discrete

c

65 = l – 15d; continuous

d

65 = l – 15d; discrete

Answer 1

l = 65 - 15d, discrete

Explanation:

per the word problem, the original length of the bread is 65cm and it decreases 15cm per day; therefore

l = 65 - 15d

the graph is discrete because up to a certain point it will stop because you cannot have negative length.
