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, 1, after d days. What is the equation of the scenario? Is
the graph of the equation continuous or discrete?
165 - 15d, discrete
165 - 15d, continuous
65 = 1 - 15d, discrete
65 = 1 - 15d, continuous

Answer 1

l = 65 – 15d; discrete

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

`l=65-15d`; discrete.

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.
