4. Let c (t) be the number of customers in a department store t hours after 8 A. M. Explain the meaning

of each statement

a. c) = 10

.

b. (6) = c (7)

c. c (k) = 0

d. (4) > 0 (3)

See explanation below.

Step-by-step explanation:

a) c (0) = 10

Here, t = 0 and c (0) = 10

At 8 A. M., there are 10 customers.

b) c (6) = c (7)

6 hours after 8 am is 2pm

7 hours after 8 am is 3pm

They are equal. So it means

There are the same number of customers at 2pm and at 3pm

c)

c (k) = 0

There are no customers, k hours after 8 am

d)

c (4) > c (3)

4 hours after 8 am is 12pm

3 hours after 8 am is 11am

This means:

The number of customers at 12pm is greater than the number of customers at 11am
