Question

Diep buys a 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?

a. l=65-15d; discrete
b. l=65-15d; continuous
c. 65=l-15d; discrete
d. 65=l-15d; continuous

Answer 1

a. l = 65-15d; discrete

Explanation:

Answer 2

a. l = 65-15d; discrete

Explanation:

The length starts at 65 and decreases by 15 each day. A suitable equation expresses this fact:

l = 65 -15d

The number of days is discrete, so the values of d and l will be discrete.
