Third calculation:
Burgers + Burgers + Boy = 13
We know the boy is 5 and we have 4 burgers, so:
2 x Burger + 2 x Burger + 5 = 13
→ 4 x Burger = 8
→ Burger = 2
This implies Burger is 10
Final calculation:
Shoe + Boy with 2 burgers and shoes + Burger = ?
→ Shoes/2 + (Boy + 2 x Burger + Shoes) x Burger = ?
→ 10/2 + (5 + 2 x 2 + 10) x 2 = ?
→ 5 + (5 + 4 + 10) x 2 = ?
→ ? = 43
