Find the average number of dogs seen per week and then multiply that number by 5 to find the best estimate of the total number of dogs seen over 5 weeks.

To do so, find the total number of dogs that were seen and divide that number by the total amount of weeks.

To find the total amount of dogs that were seen, multiply the number of dogs seen per week times the number of weeks and add them all:

Number of dogs * number of weeks:


\begin{gathered} 1*1=1 \\ 2*2=4 \\ 3*10=30 \\ 4*13=52 \\ 5*6=30 \\ 6*5=30 \\ 7*3=21 \end{gathered}

Then, the total amount of dogs that were seen, is:


1+4+30+52+30+30+21=168

Divide the total amount of dogs seen on 40 weeks over 40 to find the average number of dogs seen per week:


(168)/(40)=4.2

Multiply 4.2 times 5 to find an estimate of the number of dogs seen in the next 5 weks:


4.2*5=21

Therefore, the best estimate of the total number of dogs Sidney will se during the next 5 weeks, is:


21
