You can explain how you can use rounding or compatible numbers to see if your answer is reasonable by saying, "Rounding helps to see if your answer is reasonable. This is so because if the number you estimated was close to the answer it is a reasonable answer." I hope this helps you (:

Step-by-step explanation:
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.
