A person has a gift card for [tex]$40.00 at a gift shop. They want to buy an item for $[/tex]13.50 and some other items priced at $3.25 each. All prices include taxes.

Which inequality can be used to solve for how many additional items can be purchased?

A. [tex]\( 3.25x + 13.50 \leq 40 \)[/tex]
B. [tex]\( 3.25x + 13.50 \geq 40 \)[/tex]
C. [tex]\( 13.50x + 3.25 \leq 40 \)[/tex]
D. [tex]\( 13.50x + 3.25 \geq 40 \)[/tex]


Sagot :

To solve the problem of determining which inequality can help us figure out how many gifts can be bought with a gift card of [tex]$40.00, given some expenditures, let's break down the problem step-by-step. 1. Identify the Total Amount Available: - The total amount on the gift card is $[/tex]40.00.

2. Identify the Fixed Cost:
- There is a fixed amount of [tex]$13.50 to be spent for oneself. 3. Identify the Variable Cost: - Each gift for friends costs $[/tex]3.25, which we'll denote as [tex]\(3.25x\)[/tex], where [tex]\(x\)[/tex] represents the number of gifts bought.

4. Formulate the Total Cost:
- The total cost comprises the fixed cost plus the variable cost.
- Therefore, the total cost can be written as [tex]\(3.25x + 13.50\)[/tex].

5. Formulate the Inequality:
- The total cost must not exceed the amount on the gift card.
- Thus, we need to express that [tex]\(3.25x + 13.50\)[/tex] should be less than or equal to $40.00.

6. Translate the Description into an Inequality:
- Combining the above information, we get the inequality:
[tex]\[3.25x + 13.50 \leq 40\][/tex]

Based on the steps above, the correct inequality that can be used to solve for how many gifts can be bought is:

[tex]\[ \boxed{3.25x + 13.50 \leq 40} \][/tex]

So, the correct answer is:

A. [tex]\( 3.25x + 13.50 \leq 40 \)[/tex]
