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

(x, y)→(x − 8, y − 7)
