The price of collection of novels before taxes was $409.10.

Step-by-step explanation:

Given:

Ava bought a collection of hardcover novels and paid $450 including sales tax.

The sales tax is 10%.

Now, to find the price of collection of novels before taxes.

Let the price of collection of novels before sales tax be .

The price of collection of novels including sales tax = $450.

Rate of sales tax = 10%.

Now, to get the price before sales tax by putting an equation:

$x=450-10\%\ of\ x$

$x=450-\frac{10}{100} \times x$

$x=450-0.10\times x$

x=450-0.10x

Adding both sides by 0.10 we get:

1.10x=450

Dividing both sides by 1.10 we get:

$x=\$409.10.$

Therefore, the price of collection of novels before taxes was $409.10.
