I need some help please.
Which is the better buy? Explain.
$1.49 for 3 ft.
$.69 for 18 in.
18 in is half of 3 ft , so the price of 3 ft should be twice that of 18 in
1.49 / 3 = 0.50 per foot
.69/1.5 = 0.46 per foot
To determine which is the better buy, we need to compare the prices per unit length for both options. Let's calculate the cost per foot for each option:
Option 1:
Price: $1.49
Length: 3 ft
Cost per foot = Price / Length
Cost per foot = $1.49 / 3 ft
Option 2:
Price: $0.69
Length: 18 in
First, we need to convert inches to feet. There are 12 inches in a foot.
Length in feet = Length (in inches) / 12
Length in feet = 18 in / 12
Length in feet = 1.5 ft
Cost per foot = Price / Length
Cost per foot = $0.69 / 1.5 ft
Now, let's calculate the cost per foot for both options:
Option 1:
Cost per foot = $1.49 / 3 ft = $0.50/ft
Option 2:
Cost per foot = $0.69 / 1.5 ft = $0.46/ft
Comparing the cost per foot, we can see that Option 2, which is $0.69 for 18 inches, is the better buy. It has a lower cost per foot ($0.46/ft) compared to Option 1 ($0.50/ft).
