Explanation: in line 3 each set of two whistles is equal to 4, which means that each whistle is worth 2. In line 4 the girl is not wearing a whistle around her neck (like she was in lines 2 and 3) so you subtract the value of one whistle from the value of the girl. So it ends up being 10 (pair of shoes) + ( 3 (girl minus the Whistle value) x 2 (one whistle))
10 + 10 + 10=30
10+5+5=20
5+4+4=13
10+5+2=17
Wrong answer..HaHa
Edited. 😁
Guess again😁
Lol. I didn't notice the multiplication sign earlier. My bad
10 + 10 + 10 = 30
10 + 5 + 5 = 20
5 + 4 + 4 = 13
10 + (3 x 2) = 16

Wowo you are right!
My guess is that the answer is 30.
10+5*4=30
