Answer:
11.95 dollars
Step-by-step explanation:
Cost of one LED bulb = 6.95 dollars
Cost of changing one bulb = 3 dollars
Life of each bulb = 5 years.
In 10 years, only one time after 5 years the bulbs would have been changed
Hence cost of 100 lamps = 695 and
cost of changing once = 500
Total cost = 1195 dollars for 11 years
Divide this by 10 years to get average cost per year
Cost of 100 lamps per year = 1195/100 = 11.95 dollars
5h 30m + 6h 6m + 6h 30m = 17 hours and 66 minutes or 18 hours and 6 minutes.
1,110 minutes total.
Hope I helped! :)
<h2>How you add and subtract with numbers ?</h2><h2 /><h2><u>EXPLANATION :</u></h2><h2><u /></h2>
To add 1 to another number, add 10 and then subtract 1: 1 + 10 = 9 + 10 - 1 = 19.
Answer: well, technically you add but.... the answer is 11. Since it's a negative, one way to find the answer is to subtract 40 from 29, which is 11.
Step-by-step explanation:
It’s 15 so greater than 10 but less than 100
