Answer :

Assuming the question might be around counting or incrementally tracking something, I'll craft a step-by-step solution for the number of computers example earlier, devoid of context about the table shown here.

1. Determine the number of computers initially available: We start with an initial number of computers, which is 9. This initial quantity lays the foundation of our calculation.

2. Identify the rate at which new computers are added: Next, we identify how many new computers are added each day. This rate is 5 computers per day.

3. Specify the time duration: Determine the number of days over which the addition of computers occurs. In this case, we are considering a duration from Monday to Thursday. Since this period includes 4 days, we have a 4-day duration to consider.

4. Calculate the total number of new computers added over the specified period: Multiply the number of computers added each day by the number of days. The calculation is as follows:
[tex]\[ \text{Computers added} = 5 \, (\text{computers/day}) \times 4 \, (\text{days}) = 20 \, \text{computers} \][/tex]

5. Sum the initial number and the added number of computers to find the total available: Finally, add the initial number of computers to the total number of new computers added to find out the final available number of computers:
[tex]\[ \text{Total computers} = 9 \, (\text{initial}) + 20 \, (\text{added}) = 29 \, \text{computers} \][/tex]

Therefore, the total number of new computers added is 20, and the final total number of computers available by Thursday is 29.
