Laila is laying a path down for a new driveway. The store three types of pavers 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 2and half as many as paver 3. Paver 2 costs $2.50 each. Paver 3 costs $0.75. Which paver will be the best buy?
To determine the best buy, we need to compare the cost per paver for each option.
1) For paver 1, it costs $1.49 per paver.
2) For paver 2, she needs twice as many as paver 1, so she would need 2 * $1.49 = $2.98 worth of pavers. Thus, paver 2 costs $2.50 per paver.
3) For paver 3, she needs half as many as paver 1, so she would need 0.5 * $1.49 = $0.745 worth of pavers. Thus, paver 3 costs $0.75 per paver.
Comparing the costs, paver 1 costs $1.49, paver 2 costs $2.50, and paver 3 costs $0.75 per paver. Therefore, paver 3 is the best buy as it has the lowest cost per paver.
To determine which paver is the best buy, we need to compare the prices of each paver. Let's break it down step by step:
1. Paver 1 costs $1.49 each.
2. Paver 2 costs $2.50 each.
3. Laila needs twice as many pavers as paver 2, so she would need 2 x $2.50 = $5 worth of pavers for every paver 2.
4. Laila needs half as many pavers as paver 3, so she would need 0.5 x $0.75 = $0.375 worth of pavers for every paver 3.
Now, let's calculate the total cost based on the number of pavers needed:
For paver 1: For simplicity, let's assume Laila needs "x" number of paver 1.
Total cost for paver 1 = x x $1.49 = $1.49x
For paver 2: Laila needs 2 times as many pavers as paver 2.
Total cost for paver 2 = $2.50 x 2 = $5
For paver 3: Laila needs half as many pavers as paver 3.
Total cost for paver 3 = $0.375
Now, let's compare the total costs:
If Laila needs the same number of pavers for each type (let's assume "x" pavers for each):
- Total cost for paver 1: $1.49x
- Total cost for paver 2: $5x
- Total cost for paver 3: $0.375x
Since paver 3 has the lowest cost per paver, it would be the best buy for Laila.
Therefore, paver 3 is the best buy.
To determine which paver will be the best buy, we need to calculate the total cost of each option based on the given information.
Let's start by finding the quantity of each paver needed:
- Laila needs twice as many pavers as paver 2, so if she needs x number of pavers for paver 2, she will need 2x pavers for paver 1.
- Laila needs half as many pavers as paver 3, so if she needs x number of pavers for paver 3, she will need 0.5x pavers for paver 1.
Now, let's calculate the total cost for each type of paver:
- For paver 1: Total cost = (Price per paver) x (Quantity needed)
Total cost = $1.49 x 2x (since she needs twice as many as paver 2) = $2.98x
- For paver 2: Total cost = (Price per paver) x (Quantity needed)
Total cost = $2.50 x x (quantity needed for paver 2) = $2.50x
- For paver 3: Total cost = (Price per paver) x (Quantity needed)
Total cost = $0.75 x 0.5x (since she needs half as many as paver 3) = $0.375x
From the calculations above, we can see that the total cost for each paver depends on the variable "x". To determine which paver is the best buy, we need to compare the coefficients of "x" for each option.
Comparing the coefficients:
- Paver 1: $2.98x
- Paver 2: $2.50x
- Paver 3: $0.375x
Since the coefficients represent the cost per unit, we can conclude that the paver with the smallest coefficient will be the best buy. In this case, Paver 3 has the smallest coefficient of $0.375x, making it the best buy in terms of price.
Therefore, Paver 3 is the best option for Laila in terms of cost.
