Explanation:

Sure, let’s break down your question step by step:

- First, replace the letters with their math symbols:

- J = × (multiply)

- K = – (subtract)

- I = ÷ (divide)

- L = + (add)

So, the equation:

29 J 7 K 168 I 4 L 71 K 39 L 14 J 2

Becomes:

29 × 7 – 168 ÷ 4 + 71 – 39 + 14 × 2

Let’s solve this in order of operations (multiplication/division before addition/subtraction):

- 29 × 7 = 203

- 168 ÷ 4 = 42

- 14 × 2 = 28

Now rewrite it with those results plugged in:

203 – 42 + 71 – 39 + 28

Now just move left to right:

- 203 – 42 = 161

- 161 + 71 = 232

- 232 – 39 = 193

- 193 + 28 = 221

So, here’s what you should know:

- Option 1, 221, is correct

- None of the other options match with the computed answer.
