Suppose that 23 inches of wire costs 69 cents. At the same rate how much ( in cents ) will 18 inches of wire cost?

Solution:

Given that,

23 inches of wire costs 69 cents

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

the answer should be:

a. 3, 4, and 6

b. 18, 24, and 36

c. 4.8, 6.4, and 9.6
