Answer:
B. 2
Step-by-step explanation:
We have been given that a worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip.

.
Since each carton holds 7 jugs, so number of cartoons would be
.

We can see that there are 9 completely filled cartoons and there are 5 jugs remaining, so we need
jugs.
Therefore, we need 2 jugs to fill the 10th cartoon and option B is the correct choice.

Answer:

Step-by-step explanation:
Since emails arrive at a constant rate of 22 per day, the equation for n-th term can be modeled by a linear relationship of general form:

In this case, E₀ is the initial number of emails unread, 8, k is the rate at which emails arrive, 22 per day, and t is the number of days passed.
At t=n, the number of unread emails is:
