Respuesta :

Cost of 18 inches of wire is 54 cents

Solution:

Given that,

23 inches of wire costs 69 cents

Find the cost of 1 inch of wire

[tex]\text{cost of 1 inch of wire} = \frac{69}{23}\\\\\text{cost of 1 inch of wire} = 3[/tex]

At the same rate how much ( in cents ) will 18 inches of wire cost?

Cost of 18 inches of wire = 18 x cost of 1 inch of wire

Cost of 18 inches of wire = 18 x 3

Cost of 18 inches of wire = 54

Thus cost of 18 inches of wire is 54 cents
