The problem presented in the image is a straightforward percentage discount calculation. The question asks how much should be paid for a computer that is normally priced at $1200 but is being sold today with a 30% discount.

### Step-by-step solution:

1. **Original price of the computer**: $1200.
2. **Discount percentage**: 30%.

To calculate the discount amount:
\[
\text{Discount Amount} = \text{Original Price} \times \frac{\text{Discount Percentage}}{100}
\]
\[
\text{Discount Amount} = 1200 \times \frac{30}{100} = 1200 \times 0.30 = 360
\]

So, the discount is $360.

3. **Final price**:
\[
\text{Final Price} = \text{Original Price} - \text{Discount Amount}
\]
\[
\text{Final Price} = 1200 - 360 = 840
\]

### Answer:
You should pay **$840** for the computer.
