​

Answer 1

Answer:460

Step-by-step explanation:

Answer 2

The store had 460 DVDs initially.

• An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C.
• •  Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Here. according to the given information, we are given that,

A DVD store sells 30% of it's DVDs.

Let the total number of DVDs be x.

Then, the store could sell $\frac{30x}{100}$ of the DVDs.

Then, we get,

$\frac{30x}{100}+322 = x$

Or, $322 = \frac{100x-30x}{100}$

Or, $322 = \frac{70x}{100}$

Or, x = 460.

Hence, the store had 460 DVDs initially.
