find each unit price, witch is the better buy, explain your answer.

wire: $1.49 for 3 ft (36 inches)
wire: $0.69 for 18 inches

Respuesta :

1.49÷36 is 0.04
0.69÷18 is 0.03

$0.69 for 18 inches is the better buy
$0.69 for 18 inches is better because 18 + 18 = 36

so .69 + .69 = $1.38

Hope this helps
