Studdy Solution

STEP 1

1. Bold bought a total of 9 items, which include shirts and pants.
2. Each shirt costs 12000 төгрөг.
3. Each pair of pants costs 20000 төгрөг.
4. Bold bought $x$ pairs of pants.
5. We need to find out how much money was spent on shirts.

STEP 2

1. Determine the number of shirts purchased.
2. Calculate the total cost of the shirts.

STEP 3

Determine the number of shirts purchased.
Since Bold bought a total of 9 items and $x$ of them are pants, the number of shirts is:
$\text{Number of shirts} = 9 - x$

STEP 4

Calculate the total cost of the shirts.
Each shirt costs 12000 төгрөг. Therefore, the total cost for the shirts is:
$\text{Total cost for shirts} = 12000 \times (9 - x)$
The total amount spent on shirts is:
$\boxed{12000 \times (9 - x)}$
