Each LED bulb, along with installation labor, is priced at
.. $6.95 +$3 = $9.95
For 100 bulbs over a span of 10 years, that equals (100*10) = 1000 bulb·years. At $9.95 per bulb, 5 bulb·years are obtained, and thus the projected total cost for 1000 bulb·years is
.. (1000 b·y)*($9.95/(5 b·y)) = $1990
In summary, for a decade, the installation and changes of 200 bulbs in 100 lamps amount to $1990. Therefore, the yearly cost is...
.. $1990/(10 yr) = $199/yr
Answer:
the expression is -64937.4.5.53.94x
Step-by-step explanation:
The variable representing the total number of songs is x, hence twice that quantity is 2x, and subtracting three results in -3, which leads to the expression 2x - 3.
225 goes to the bakery

<span>Given that each individual can receive a single prize, there are 50*49*48= 117600 different ways to allocate the prizes. The first award can be given to any of the 50 participants, the second to one of the remaining 49, and the last to one of the leftover 48. Multiplying these options together provides the solution.</span>
