I missed you on "bags of weed"3 pairs of shoes = 30. 1 shoe = 10/2 = 5

1 pair of shoes + 2 guys = 20. 1 pair of shoes = 10, so 1 guy = 10/2 = 5

1 guy + 4 bowls of weed = 13. 1 guy = 5, so 1 bowl of weed = 8/4 = 2

There's a guy in the middle of the 4th row with a pair of shoes and 2 bowls of weed.

Ergo, the combination must be 1 guy + 1 pair of shoes + 2 bowls of weed.

From above we know a guy = 5, a pair of shoes = 10 and 2 bowls of weed = 4

So this particular guy = 5+10+4 = 19

We have a singular shoe, so that's 5.

We have a single bowl of weed, so that's 2.

So it's 5 + 19 * 2 = ?

For anyone who paid attention in grade 7 math class, you guys should be familiar with the order of operations, or BEDMAS. This stands for Brackets>Exponents>Division>Multiplication>Addition>Subtraction.

Multiplication takes precedent over addition.

Ergo, it's 5 + 38 = 43.
