Formula in terms of length in meters for the international division:

cost = 0.0274 * (length of wire in meters)

Step-by-step explanation:

The given formula for the cost of copper wire is:

cost = 0.09 * (length of wire in ft)

Sales manager needs a formula to find the cost of the copper wire in terms of meters. For that we have to convert the length of wire in ft to length of wire in meter.

We know that  1 ft = 0.3048 meter, using this in cost formula:

cost = 0.09 * (length of wire in ft) = 0.09 * (0.3048 * length of wire in meter)

cost = 0.09 * 0.3048 * (length of wire in meters)

cost = 0.0274 * (length of wire in meters)
