Question

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

Answer 1

Answer:

l = 65 – 15d; discrete

Step-by-step explanation:

15 is the centimeters he cuts off every day, you have to multiply that by D that´s the nomber of days, in order to calculate how much baguette does he have left.

If 4 days have passed, the anser would be 5 centimeters:

I=65- 15(4)= 65-60= 5

Answer 2

Answer:

$l=65-15d$; discrete.

Step-by-step explanation:

Let d represent number of days.

We have been given that for lunch every afternoon, Diep cuts 15 centimeters of bread for his  sandwich. The length of loaf cut in d days would be $15d$.

Diep bought a baguette loaf of bread 65 centimeters long. The length of loaf of bread after d days would be initial length minus amount of loaf cut in d days that is:

$65-15d$

Since $l$ represents length of bread, so our equation would be: $l=65-15d$

Therefore, the expression $l=65-15d$ represents the given scenario.

The variable d represents number of days and days cannot be fractional. We can take only whole number of days, therefore, the graph of the equation would be discrete.
