Explanation:

Step1: Find last - year numbers

From the bar graph, last year: woodwind had \(12\) kids, brass had \(8\) kids, percussion had \(10\) kids.

Step2: Calculate this - year numbers

Brass doubled: \(8\times2 = 16\) kids.
Woodwind had \(3\) kids leave: \(12 - 3=9\) kids.
Percussion stayed the same: \(10\) kids.

Step3: Sum up this - year numbers

Total number of kids \(=9 + 16+10\)
\(=35\)
