Refer to the image below.

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

Explicación paso a paso:

Debemos encontrar la ecuación para poder graficar.

De acuerdo a la afirmación, la ecuación sería:

E = v * t - Ei

Siendo Ei (20) la elevación inicial, t el tiempo transcurrido y la velocidad de 4, realizamos la sustitución y obtenemos:

 E = 4 * t - 20

A continuación, debemos calcular los valores correspondientes:

E (0) = 4 * 0 - 20 = -20

E (1) = 4 * 1 - 20 = -16

E (2) = 4 * 2 - 20 = -12

E (3) = 4 * 3 - 20 = -8

E (4) = 4 * 4 - 20 = -4

E (5) = 4 * 5 - 20 = 0

Si graficamos, tendríamos la imagen anexa:
