Answer:
D: 48
Step-by-step explanation:
Daily cost of production; c(x) = 200 + 16x
when the number of complete products manufactured is 5, the cost is:
c(5) = 200 + 16(5)
= 200 + 80
= 280
c(5) = 280
When the number of complete products manufactured is 8, the cost is:
c(8) = 200 + 16(8)
= 200 + 128
= 128
c(8) = 328
Average rate of change = c(8) - c(5)
= 328 - 280
= 48
Thus, the average rate of change is 48.
Answer:
See, that doesn't make sense.
First of all, 4 is the only number equal to 4. Sp, it'd be 9+4 = 13
Then I'm assuming you're also subtracting 4 from 13, so the answer would be 9.
Hope this helped, have a nice day.
