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

65 = l - 15d; continuous

Explanation:

Got it right on the test :)

Answer 2

65 = l - 15d; continuous

65 is the loaf of bread, and -15d is when Diep cuts 15cm of the bread for his lunch.

The graph is continuous because it is following a decreasing pattern of -15 per day. If the information were put on a data graph the line formed would be straight.
