we have that
the cost is
y=31.27x+34573
and the revenue is
y=76.17x
Remember that
The Break-even point is when the cost is equal to the revenue
so
Equate both equations
76.17x= 31.27x+34573
Solve for x
76.17x-31.27x=34573
44.9x=34573
x=770
Find out the value of y
y=76.17(770)=58,650.90
therefore
the answer is the ordered pair (770,58,650.90)
