.Since the old number of patients is 960
Since it is increasing by 25%, then
We will find the amount of 25% of 960, then add it to 960
[tex]\begin{gathered} I=\frac{25}{100}\times960 \\ I=240 \end{gathered}[/tex]Add it to 960 to find the new number of patients
[tex]\begin{gathered} N=960+240 \\ N=1200 \end{gathered}[/tex]Dr Wells saw 1200 patients
