Question

Find the break-even point by solving each system using substitution. Show all work.
20. Cost: y = x + 100

Revenue: y = 3x



Break-even Point:

Answer 1

@abb0t any chance you know how to do this?

Answer 2

This is a system. You are already given \(y\), function. Simply substitute for \(y\) and solve for \(x\)

Answer 3

\(3x=x+100\)

Answer 4

oh so 2x=100
x=50

Answer 5

The break even point is where cost = revenue.
Since you have y = x + 100 and y = 3x, just set
x + 100 = 3x and solve for x.

Answer 6

Yes

Answer 7

x=50 but is 50 the break even point?
