Question

show that 50x/(20-x) = 1000/(20-x)-50

Answer 1

\[\frac{ 50x }{20-x }=\frac{ 1000 }{ 20-x }-50\]

Answer 2

450x + 1000 = 500x
1000 = 50x
20 = x

there must be 20 in sales

C = 450(20) + 1000 = 10,000
R = 500(20) = 10,000

any sales above 20 means that revenue will be greater than cost, and the business will make a profit
