Question

A manufacturing company builds construction machinery. It sells 10 machines for $18,100 and 20 machines for $26,600. Which equation models the revenue, R(x), as a linear function of the number of machines built, x ?

Select one:
A. R(x)=750x−10100
B. R(x)=450x+7200
C. R(x)=1200x−4500
D. R(x)=850x+9600

Answer 1

Answer:

$\frac{26600}{20} - \frac{18100}{10}$

$1330 - 1810 = - 480$

So,

Option D

D. R(x)=850x+9600
