Answer

Explanation:

Step1: Calculate the price after discount

The original price of the computer is $1800$ and the discount is $30%$. The price after discount is $1800\times(1 - 30%)=1800\times0.7 = 1260$.

Step2: Calculate the total tax rate

The GST is $5%$ and the PST is $7%$, so the total tax rate is $5%+7% = 12%$ or $0.12$ in decimal form.

Step3: Calculate the amount of tax

The tax amount is $1260\times0.12=151.2$.

Step4: Calculate the final price

The final price of the computer is the price after - discount plus the tax amount, so $1260 + 151.2=1411.2$.

Answer:

$1411.2$
