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? l = 65 – 15d; discrete l = 65 – 15d; continuous 65 = l – 15d; discrete 65 = l – 15d; continuous

Answer 1

The correct answer is:

l = 65 – 15d; discrete

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
