There are 36 inches in a yard. So, 54 inches is 54/36 = 1.5 yards.
If specialty-treated wire sells for 70 cents per yard, then the cost of 1.5 yards would be:
1.5 yards * 70 cents/yard = 105 cents or $1.05 (rounded to the nearest cent)
Therefore, the cost of 54 inches (1.5 yards) of specialty-treated wire is $1.05.
