Question 1

Conor is going to the movie theater. A ticket to a movie costs t dollars, and there is a
15% amusement tax on each ticket.
Conor buys a ticket to see a movie. Write two expressions in terms of t
showing his total cost.

5 answers

To determine Conor's total cost for the movie ticket, we need to consider both the cost of the ticket and the amusement tax.

  1. Cost of the ticket: This is simply \( t \) dollars.

  2. Amusement tax: The amusement tax is 15% of the ticket price. This can be expressed as: \[ 0.15t \]

  3. Total cost: The total cost for Conor will therefore be the cost of the ticket plus the amusement tax. This can be expressed as: \[ t + 0.15t \]

This simplifies to: \[ t(1 + 0.15) = t \cdot 1.15 = 1.15t \]

So, the two expressions showing Conor's total cost in terms of \( t \) are:

  1. \( t + 0.15t \)
  2. \( 1.15t \)

Both expressions represent the same total cost.

Choose a value for t greater than $12 and less than $13. Use one of the
expressions you wrote in part a to find Conor’s total cost, rounded to the
nearest penny. keep your answer short

Let's choose \( t = 12.50 \).

Using the expression \( 1.15t \) to find Conor’s total cost:

\[ \text{Total Cost} = 1.15 \times 12.50 = 14.375 \]

Rounding to the nearest penny, Conor's total cost is:

\[ \text{Total Cost} \approx 14.38 \]

Suppose that Conor’s total cost to see the movie is greater than $17.50 and
less than $20. What could be a value of t to make that possible? keep answer short

To find a value of \( t \) such that \( 17.50 < 1.15t < 20 \), we can manipulate the inequalities:

  1. For the lower bound: \[ 1.15t > 17.50 \implies t > \frac{17.50}{1.15} \approx 15.22 \]

  2. For the upper bound: \[ 1.15t < 20 \implies t < \frac{20}{1.15} \approx 17.39 \]

Thus, \( t \) should be in the range: \[ 15.22 < t < 17.39 \]

A possible value of \( t \) in this range could be \( t = 16 \).
