Answer:
c = 220
Step-by-step explanation:
f(x) = cx + d
For the first equation
f(50) = 27,000
Substitute the value of x that's 50 into the expression
That's
50c + d = 27,000
For the second equation
f(100) = 38,000
Substitute the value of x that's 100 into the expression
We have
100c + d = 38,000
Subtract the first equation from the second one to eliminate d
That's
100c - 50c + d - d = 38,000 - 27,000
50c = 11,000
Divide both sides by 50
We have the final answer as
c = 220
Hope this helps you
