Question

20.

What equation models the data in the table if d = number of days and c = cost?

Days
2
3
5
6
Cost
16
24
40
48

A. d = 8c

B. c = d + 8d

C. c = 8d

D. c = d + 8

Answer 1

The answer is C. 8*2=16. 8*3=24. 8*5=40 8*6=48

Answer 2

Answer: C. c = 8d

I'm gonna go with c = 8d

Step-by-step explanation: c = 8d

D) c = 8d

The cost is a direct variation of the days by a factor of 8.

Answer:

Correct option is:

c=8d

Step-by-step explanation:

Days Cost

2 16=2×8

3 24=3×8

5 40=5×8

6 48=6×8

As we can clearly observe from the table above that if d is the number of days then the cost c is written as:

c=8d

Hence, Correct option is:

c=8d
