A group of friends wants to go to the amusement park. They have no more than $235 to spend on parking and admission. Parking is $7, and tickets cost $28.50 per person, including tax. Write and solve an inequality which can be used to determine pp, the number of people who can go to the amusement park.

Answers

228/28.50= 8 that should be right!

The solution of the inequality for the number of people (p) who can go to the amusement park will be;

⇒ p < 8

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Given that;

They have no more than $235 to spend on parking and admission.

And, Parking is $7, and tickets cost $28.50 per person, including tax.

Now,

Let the number of people who can go to the amusement park = p

So, We can formulate;

⇒ 28.50p + 7 < 235

Solve for p as;

⇒ 28.50p < 235 - 7

⇒ 28.50p < 228

⇒ p < 228/28.50

⇒ p < 8

Thus, The solution of the inequality for the number of people (p) who can go to the amusement park is;

⇒ p < 8

You buy a flight to California for $305.72. The tax is 7.65%. What is the final cost of the ticket?

Show work and use method

Answers

Answer:309.83

Step-by-step explanation:

The final cost of the flight ticket $329.10758.

Given that, the cost of flight ticket is $305.72 and tax=7.65%.

What is the tax?

Taxes are mandatory contributions levied on individuals or corporations by a government entity—whether local, regional, or national. Tax revenues finance government activities, including public works and services such as roads and schools, or programs such as Social Security and Medicare.

Now, tax = 7.65% of 305.72

= 7.65/100 × 305.72

=0.0765 × 305.72

=$23.38758

Total cost = 305.72+23.38758

=$329.10758

Therefore, the final cost of the flight ticket $329.10758.

Step-by-step explanation:

You can make a ratio out of this!

2 / x = (x+1) / 3

1. Cross multiply^

2. 2 * 3 = x (x+1)

3. 6 = x^2 + x

3. x^2 + x - 6

4. Factor^

5. (x-2)(x+3)

6. x - 2 = 0 turns into x = 2

7. x + 3 = 0 turns into x = -3

8. There's not way to measure -3 yet, so you are left with x = 2
