Laila needs to compare the prices of all the pavers to determine which one is the best buy.
Paver 1 costs $1.49 each.
Paver 2 costs $2.50 each.
Paver 3 costs $0.75 each.
Laila needs twice as many paver 2 stones as paver 1 stones. This means if Laila needs N paver 1 stones, she will need 2N paver 2 stones.
Laila needs half as many paver 3 stones as paver 1 stones. This means if Laila needs N paver 1 stones, she will need 0.5N paver 3 stones.
To find out the best buy, we need to compare the total cost for each paver option.
For paver 1: total cost = $1.49 * N
For paver 2: total cost = $2.50 * 2N = $5 * N
For paver 3: total cost = $0.75 * 0.5N = $0.375 * N
The paver with the lowest total cost will be the best buy. Comparing the total costs, we can see that paver 3 is the cheapest option with a total cost of $0.375 * N.
Therefore, paver 3 will be the best buy.
