Find each unit price. Which is the better buy? Explain.

Question

Electrical wire:

$1.49 for 3 ft.

$.69 for 18 in.

Answer 1

divide cost/quantity

$1.49/3ft = $0.4967/ft

and similarly for the other one. Then compare

Answer 2

depends on how much wire you need.
one is almost 50cents per foot, the other is almost 46 cents per foot.

Answer 3

How did you get 46?

Answer 4

0.69 / 1.5 = 0.46

Answer 5

1.49/3 = x/1
cross multiply
3x = 1.49
x = 1.49/3
x = 0.496 (rounds to 50 cents per foot)

.69/18 = x/1
cross multiply
18x = .69
x = .69/18
x = .038 per inch
12 inches in a foot
x = .038(12) = 0.456 (rounds to 46 cents per foot)

Answer 6

1.49/3 = 0.50 per foot
0.69/1.5 = 0.46 per foot

.69 is the better buy
