You need at least [tex] \$ 60 [/tex] to buy a new video game. You have saved [tex] \$ 25 [/tex]. Which inequality models how much more you must save?

A. [tex] n + 25 \leq 60 [/tex]
B. [tex] n - 25 \geq 60 [/tex]
C. [tex] n + 25 \geq 60 [/tex]
D. [tex] 60 + 25 < n [/tex]

Answer :

To find out how much more you need to save to buy the video game, you can set up an inequality. Let's break it down:

1. Identify what you know:

- You already have saved [tex]$25.
- You need at least $[/tex]60 to buy the video game.

2. Set up the inequality:

You need to determine how much more money, represented by [tex]\( n \)[/tex], you need to save. Since you want the total amount of money (your savings plus what you still need) to be at least [tex]$60, the mathematical inequality looks like this:

\[
n + 25 \geq 60
\]

This inequality states that the amount you already have plus the additional amount you need to save should be greater than or equal to $[/tex]60.

3. Solve for [tex]\( n \)[/tex]:

To find out how much more you need to save, subtract 25 from both sides of the inequality:

[tex]\[
n + 25 - 25 \geq 60 - 25
\][/tex]

Simplifying, we get:

[tex]\[
n \geq 35
\][/tex]

Thus, you need to save at least $35 more to be able to purchase the video game. Hence, the correct inequality is [tex]\( n + 25 \geq 60 \)[/tex].
