Ahlia Technologies, which manufacturers high-technology instruments for spacecraft, is considering the sale of a navigational unit to a private company that wishes to launch its own communications satellite. The company plans to purchase 8 units, although it would also consider buying 16 units. Ahlia has started a chart relating labor time required to units produced:

Units Produced (X)	Time Required to Produce the Xth Unit
1	5,000 hours
2	4,500 hours
4	4,050 hours
8	?
16	?

Instructions:

1. Complete the chart by filling in the labor time required to produce 8 and 16 units. (show your calculations)
2. Assume that labor time costs $140 per hour. Compare the cost of production the 1^st unit to the cost of producing the 16^th unit. what is the percentage of the cost of the 16^th unit to the cost of the 1^st unit?
