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 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.
To determine which paver will be the best buy, we need to calculate the total cost of each paver based on the given quantities.
Let's assume Laila needs "x" paver stones of paver 2. As per the given information, she will need twice as many paver 2 stones, so she will need 2x paver 1 stones. Additionally, she will need half as many paver 3 stones, so she will need x/2 paver 3 stones.
Therefore, the total cost of pavers 1, 2, and 3 can be calculated as follows:
Cost of paver 1: 2x * $1.49 = $2.98x
Cost of paver 2: x * $2.50 = $2.50x
Cost of paver 3: x/2 * $0.75 = $0.375x
Now, we can compare the total costs of each paver:
Cost of paver 1: $2.98x
Cost of paver 2: $2.50x
Cost of paver 3: $0.375x
The best buy would be the paver with the lowest cost per paver. In this case, paver 3 costs the least, at $0.375x per paver.
Hence, the best buy is paver 3, which costs $0.375 per paver.
