Laila is laying a path down for a new driveway. The store has three types of paver stones that will work for her space. She needs to know which paver is the best price. Paver 1 costs $1.49 each, and she will need twice as many as paver 2 and half as many as paver 3. Paver 2 costs $2.50 each. Paver 3 costs $0.75. Which paver will be the best buy? Your answer should be a number.(1 point)

Paver .

1 answer

To determine which paver is the best buy, we need to calculate the total cost for each type of paver based on the relationships given. Let's assume the number of Paver 2 needed is \( x \).

  1. Paver 2:

    • Cost: $2.50 each
    • Quantity needed: \( x \)
    • Total cost for Paver 2: \( 2.50x \)
  2. Paver 1:

    • Cost: $1.49 each
    • Quantity needed: \( 2x \) (twice as many as Paver 2)
    • Total cost for Paver 1: \( 1.49(2x) = 2.98x \)
  3. Paver 3:

    • Cost: $0.75 each
    • Quantity needed: \( x/2 \) (half as many as Paver 2)
    • Total cost for Paver 3: \( 0.75(x/2) = 0.375x \)

Now, let's compare the total costs of each paver:

  • Total cost for Paver 1: \( 2.98x \)
  • Total cost for Paver 2: \( 2.50x \)
  • Total cost for Paver 3: \( 0.375x \)

To find the best buy, we can compare these total costs directly (without needing the value of \( x \) since it will cancel out):

  1. For Paver 1: \( 2.98x \)
  2. For Paver 2: \( 2.50x \)
  3. For Paver 3: \( 0.375x \)

Clearly, \( 0.375 < 2.50 < 2.98 \).

Therefore, the best buy is Paver 3.

Final Answer: 3
