Solve for X: Finding Number of $4.50 Paper Packs Totaling $45

Question

Lionel buys $x$ packs of paper.

The price of each pack is $4.5 and he pays a total of$ 45.

Calculate $x$ .

00:00 Find X

00:03 Price per package according to the given data

00:07 Let's mark the number of packages using the unknown X

00:10 The total amount paid

00:18 Isolate X

00:24 And this is the solution to the question

To solve this problem, we'll use a step-by-step approach:

Step 1: Set up the equation based on the problem statement.
The total cost Lionel pays is given by the formula:

$4.5x = 45$

Here, $x$ is the number of packs Lionel buys, and $4.5 is the cost per pack.

Step 2: Solve for $x$ .
To find $x$ , divide both sides of the equation by 4.5:

$x = \frac{45}{4.5}$

Step 3: Perform the division.
Carrying out the division,

$x = \frac{45}{4.5} = 10$

Therefore, Lionel buys $x = 10$ packs of paper.

$x=10$
