Question

Diep bought a baguette loaf of bread 65 centimeters long. For lunch every afternoon, he cuts 15 centimeters of bread for his sandwich. Diep 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?

Answer 1

Initially the loaf of bread was 65 centimeters long.

Everyday he cuts 15 centimeters of bread for his sandwich. He wants to know the length of the loaf of bread, l, after d, days.

If he cuts 15 centimeters everyday then he will have cut $15 \times d=15d$ centimeters of bread after 'd' days.

So the length 'l' after 'd' days is given by:

$l=65-15\times d=65-15d$

So the equation to represent the length of the bread loaf after d days is:

$l=65-15d$.

The graph of the function is continuous  because for a function to be discrete the values belonging to a set should be distinct and separate.

Answer 2

Answer:

l = 65 – 15d; discrete
