BigorU [14]

Answer:

$x = 5$

$R = C = 225$

Step-by-step explanation:

Given

$C = 15x + 150$

$R = 45x$

Required

The break even point

To do this, we make use of:

$R =C$

$45x=15x + 150$

Collect Like Terms

$45x-15x = 150$

$30x = 150$

$x = 5$

Substitute 5 for x in $R = 45x$

$R = 45 * 5$

$R = 225$

Hence, the break even point is:

$x = 5$

$R = C = 225$
