You can upgrade lighting at your factory to led bulbs that costs $6.95 each and last an average of 5 years. it costs $3.00 in labor to change a bulb. over a 10-year period, about how much will it cost per year to install led bulbs in 100 lamps and change the bulbs when they burn out? a. $140 b $200 c $440 d $700 e $1,000

Labor is $3 per bulb, there is 100 lamps, so the labor cost would be 100 x 3 = $300.

The cost of one bulb is 6.95, the total cost of bulbs is 100 x 6.95 = $695

The total fr bulbs and labor is $695 + $300 = $995

The bulbs last 5 years so, for a 10 year period you would need to change the bulbs twice so total cost for 10 years would be 995 x 2 = $1990.

To find the cost per year, divide the total cost by the number of years:
1990 / 10 = 199 per year. Round to $200 per year.
 The answer is B.
