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)
To determine the best buy, we need to calculate the total cost of each paver option.
Let's assume Laila needs x pavers of type 1.
Paver 2 is needed in twice the quantity of paver 1, so Laila needs 2x pavers of type 2.
Paver 3 is needed in half the quantity of paver 1, so Laila needs (1/2)x pavers of type 3.
The total cost of paver 1 would be $1.49 multiplied by x.
The total cost of paver 2 would be $2.50 multiplied by 2x.
The total cost of paver 3 would be $0.75 multiplied by (1/2)x.
Comparing the costs:
Total cost of paver 1 = $1.49x
Total cost of paver 2 = $2.50 * 2x = $5x
Total cost of paver 3 = $0.75 * (1/2)x = $0.375x
Comparing the paver costs, the best buy would be the paver with the lowest cost.
Therefore, the best buy is paver 3 with a cost of $0.375 per stone.
