The answer would be 7 beats
The first symbol is a quarter note which is counted as one beat, then the next two are eighth rests which are each counted as half a beat, making them together one beat. So then you would have 2 beats, and the next symbol is a half note which is counted as 2 beats making the total 4 beats. Then the next one is a half rest which again is counted at 2 beats making it 6 beats in total, then the last one is a quarter rest which, like the first symbol, is counted as one beat. Therefore the total would be 7 beats :) hope this helps!
