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?

Answer 1

Let's refer to the number of paver stones needed for paver 1 as "x".

According to the information given, paver 2 costs $2.50 each and she will need twice as many as paver 2, which means she will need 2x paver 2 stones.

Paver 3 costs $0.75 each, and she will need half as many as paver 3, so she will need 0.5x paver 3 stones.

To determine the best buy, we need to calculate the total cost for each type of paver stone.

Total cost for paver 1 = x * $1.49 = $1.49x
Total cost for paver 2 = 2x * $2.50 = $5x
Total cost for paver 3 = 0.5x * $0.75 = $0.375x

To compare the prices, we can simply compare the coefficients of x:

Paver 1: 1.49x
Paver 2: 5x
Paver 3: 0.375x

Since we are looking for the best price, the paver with the lowest coefficient of x will be the best buy. Therefore, paver 3 is the best buy as it costs $0.375x per stone.
