We are given the following information:
Sami scored 84 points in the first round
In the second round, he scored 21 points more than the first round
What do we need to calculate Sami's total score?
The very first thing we need to find is: the number of points he got in the second round
Sami scored 84 points in the first round
He scored 21 more points than that in the second round
We will represent the information using the bar model as shown below:
Therefore, the total number of points that Sami got is: 189 (shown below)
[tex]\begin{gathered} =84+(84+21) \\ =84+105 \\ =189 \end{gathered}[/tex]
