Question

Solve the two business equations for when C = R. Find the value of C and x at which this happens. Use any method you wish. C = 0.35x + 3 and R = 1.5x.
A. x = 0, C = 0
B. x 3.913, C 2.609
C. x 2.609, C 3.913
D. x = 4, C = 2

Answer 1

R = 1.5x
C = R
So C = 1.5x
Set C = 1.5x in the first equation and solve for x.

Answer 2

i get 1.85 for x

Answer 3

C = 0.35x + 3
C = R = 1.5x
Put C = 1.5x in the first equation
1.5x = 0.35x + 3
Subtract 0.35x from both sides
1.5x - 0.35x = 3
1.15x = 3
Divide both sides by 1.15
x = 3/1.15 = 2.609
Put x = 2.609 in
C = 1.5x
C = (1.5)(2.609) = 3.913

So x = 2.609, C = 3.913

Answer 4

ohh i get now thanks a lot :)
