Answer:
the new one for a: 12/21 and 15/21
the new one for b: 20/25 and 15/25
the new one for c: 20/27 and 33/27
the new one for d: 25/24 and 36/24
Step-by-step explanation:
4/7 x 3/3 equals 12/21
3/5 x 5/5 equals 15/25
11/9 x 3/3 equals 33/27
6/4 x 6/6 equals 36/24
Answer:
18,646
Step-by-step explanation:
>you can graph the equation on a calculator and see that the minimum is at the point (250, 18646) , so the minimum unit cost is 18,646
>you can use the first derivative to find the minimum
c'(x) = (0.2x²-100x+31,146)' = .4x -100
.4x-100= 0 , so x= 250
c(x=250) = 0.2(250)² -100*250 +31,146 =18,646
