x = number of units sold
cost is equal to 30 + 2.50x
sale price is 3x
c = 2.50x + 30
r = 3x
break even point is when the cost function equals the revenue function.
2.5x + 30 = 3x
subtract 2.5x from both sides of this equation to get:
3x - 2.5x = 30 which becomes:
.5x = 30
divide both sides of this equation by .5 to get:
x = 60
that's the break even point.
cost = 2.5*60 + 30 = 180
revenue = 3*60 = 180

Let x = number of kilograms of coffee powder sold
(a)
+C+=+2.5x+%2B+30+
+R+=+3x++
(b)
The breakeven point is where
+C+=+R+
+2.5x+%2B+30+=+3x+
+.5x+=+30+
+x+=+60+ kg of coffee powder sold
