High School

Kiran's family is having people over to watch a football game. They plan to serve sparkling water and pretzels. They are preparing 12 ounces of sparkling water and [tex]\sqrt{3}[/tex] ounces of pretzels per person. Including Kiran's family, there will be 10 people at the gathering.

A bottle of sparkling water contains 22 ounces and costs \[tex]$1.50. A package of pretzels contains 16 ounces and costs \$[/tex]2.99.

Let [tex]n[/tex] represent the number of people watching the football game, [tex]s[/tex] represent the ounces of sparkling water, [tex]p[/tex] represent the ounces of pretzels, and [tex]b[/tex] represent Kiran's budget in dollars.

Which equation best represents Kiran's budget?

A. [tex]12s + 3p = b[/tex]

B. [tex]12 \cdot 10 + 3 \cdot 10 = b[/tex]

C. [tex]1.50s + 2.99p = b[/tex]

D. [tex]1.50 \cdot 6 + 2.99 \cdot 2 = b[/tex]

Answer :

Sure! Let's break down the problem and find out which equation best represents Kiran's budget for the football gathering. We know the following details:

1. Number of people: Including Kiran's family, there will be 10 people.
2. Sparkling water: Each person will have 12 ounces.
3. Pretzels: Each person will have [tex]\(\sqrt{3}\)[/tex] ounces.
4. Sparkling water bottles: Each bottle contains 22 ounces and costs \[tex]$1.50.
5. Pretzel packages: Each package contains 16 ounces and costs \$[/tex]2.99.

Now, let's go through each step to solve the problem:

### Step 1: Calculate Total Ounces Needed

- Sparkling Water:
[tex]\[
\text{Total Sparkling Water} = 12 \, \text{ounces/person} \times 10 \, \text{people} = 120 \, \text{ounces}
\][/tex]

- Pretzels:
[tex]\[
\text{Total Pretzels} = \sqrt{3} \, \text{ounces/person} \times 10 \, \text{people} \approx 17.32 \, \text{ounces}
\][/tex]

### Step 2: Calculate Number of Bottles and Packages Needed

- Bottles of Sparkling Water Needed:
[tex]\[
\text{Bottles Needed} = \lceil \frac{120 \, \text{ounces}}{22 \, \text{ounces/bottle}} \rceil = 6 \, \text{bottles}
\][/tex]

- Packages of Pretzels Needed:
[tex]\[
\text{Packages Needed} = \lceil \frac{17.32 \, \text{ounces}}{16 \, \text{ounces/package}} \rceil = 2 \, \text{packages}
\][/tex]

### Step 3: Calculate Total Cost

- Cost of Sparkling Water:
[tex]\[
\text{Total Cost of Sparkling Water} = 6 \, \text{bottles} \times \$1.50/\text{bottle} = \$9.00
\][/tex]

- Cost of Pretzels:
[tex]\[
\text{Total Cost of Pretzels} = 2 \, \text{packages} \times \$2.99/\text{package} = \$5.98
\][/tex]

### Step 4: Calculate Total Budget

- Total Budget:
[tex]\[
\text{Total Budget} = \$9.00 + \$5.98 = \$14.98
\][/tex]

### Conclusion

After calculating, the best equation representing Kiran's budget is based on the total ounces and costs needed. In this case, the choice that aligns best with our steps and the calculated budget is:

- Option D: [tex]\(1.50 \cdot 6 + 2.99 \cdot 2 = b\)[/tex] which results in [tex]\(b = 14.98\)[/tex], aligning with our calculated total budget.
