Question

Trevor heads to the mall to buy three pairs of Levi jeans, each price the same amount. He also buys a Levi t-shirt that is $4 cheaper than one of the pairs of jeans. He has $150 to spend but wants to have at least $40 left. What is the price range for the slacks?

Answer 1

To find the price range for the slacks, set up an equation and solve for x. The price range for the slacks is any amount less than or equal to $30.50.

Step-by-step explanation:

To find the price range for the slacks, we can start by setting up an equation.

Let's say the price of each pair of jeans is x dollars.

The price of the Levi t-shirt is $4 cheaper than one of the pairs of jeans, so it would be (x - $4) dollars.

Since Trevor wants to have at least $40 left after making the purchases, we can set up the equation:

3x + (x - $4) + $40 ≤ $150

Now we can solve for x to find the price range for the slacks:

4x - $12 + $40 ≤ $150

4x + $28 ≤ $150

4x ≤ $150 - $28

4x ≤ $122

x ≤ $122 / 4

x ≤ $30.50

So the price range for the slacks is any amount less than or equal to $30.50.
