$ $12, 750$ $12,750$

Old purchase price: $ $3, 000$ $3,000$

Find percentage increase: $ $3, 000 \times \frac{325}{100} =$ $3,000xx325/100=$ $ $9, 750$ $9,750$

Add the percent increase to the purchase price:
$ $3, 000 +$ $3,000+$ $ $9, 750 =$ $9,750=$ $ $12, 750$ $12,750$

An increase of 325% means 425% total ($12750)

As it's stated an increase is the plus to the original condition. Therefore in this case is 100% (original price) + 325% (the increase).

You can see it form the following formula

$% = (\frac{X_{1} - X_{0}}{X_{0}}) 100$ $% = ((X_1 - X_0) / X_0)100$

Where $X_{1}$ $X_1$ is the actual value and $X_{0}$ $X_0$ is the original value

Then if we solve for $X_{1}$ $X_1$ we could have

$X_{1} = \frac{X_{0} \times %}{100} + X_{0}$ $X_1 = (X_0 xx %)/100 + X_0$

Replacing values:

$X_{1} = \frac{3000 \times 325}{100} + 3000$ $X_1 = (3000 xx 325)/100 + 3000$

$X_{1} = 12750$ $X_1 = 12750$

Or as I say in the answer

$X_{1} = 3000 \times \frac{425}{100} = 12750$ $X_1 = 3000xx425/100 = 12750$

Now you just need to add the tax, just joking...

Hope this helps
