Your answer is 8 cups of yogurt and 4 cups of juice!!!
X-y=1
x+y=3
You see the y's can cancel out. So add it together and you have:
2x=4
x=2
Now that you have x, plug it in to one of the equations to find y.
I will plug it into the first one.
(2)-y=1
-y=-1
y=1
Answer:
i thinkbit is C but im in 6th grade and at may 5 i. not there yet
(a) Net present value of machine
Pm=-C+V/(1+i)^n=37000-1000/1.08^4
=-36264.97
=-36265 (rounded to nearest dollar)
Cost of machine amortized over 4 years (annualized cost)
Ac=Pm(A/P,i,n)=-36264.97(A/P,0.08,4)=-36264.97(.08*(1.08^4)/(1.08^4-1)
=-10949.15
Expected year-end cash flow = annualized return - annualized cost =>
12000=return - 10949.15
(b) Internal rate of return of machine
=return/cost - 1
=(12000-(-10949.15)/10949.15-1
=2.096-1
=1.096
=109.6%
