$\rm⇢ \: \: - 3(8 + j) = - 16 + 5j$

$\rm⇢ \: \: - 24 - 3j = - 16 + 5j$

$\rm⇢ \: \: 5j + 3j = - 24 + 16$

$\rm⇢ \: \: 8j = - 8$

$\rm⇢ \: \: j = - 1$

Answer:

D. R(x)=850x+9600

Step-by-step explanation:

Use the given information as points on a line, and find the slope.

The two given points are (10, 18,100) and (20, 26,600).

slope = (difference in y)/(difference in x)

slope = (26,600 - 18,100)/(20 - 10)

slope = 8,500/10

slope = 850

Only choice D. has a slope of 850.

Answer: D. R(x)=850x+9600
