The table below shows the relationship between the number of dozens and the number of cookies
Number of dozens Number of cookies
5 60
7 84
9 108
1 132
Which equation could be used to find n, the number of cookies in d, the number of dozens
A.n=10d
B.n=d/10
C.n=12d
D.n=d/12
C
Right.
To find the equation that relates the number of cookies (n) to the number of dozens (d), we can observe the relationship between the given data points.
Looking at the table, we can see that as the number of dozens (d) increases, the number of cookies (n) also increases.
Let's compare the values of d and n in each row:
- When d = 5, n = 60
- When d = 7, n = 84
- When d = 9, n = 108
- When d = 1, n = 132
By examining these values, we can deduce that the number of cookies is 12 times the number of dozens.
Therefore, the correct equation that represents this relationship is:
n = 12d
Thus, option C, n = 12d, is the correct equation that can be used to find the number of cookies (n) based on the number of dozens (d).
