The table lists the total number of bags of grass seed it took to plant a certain number of lawns. All of the lawns were the same size.
Number of Lawns: 4 = 22, 5 = 27.5, 6 = 33, 7 = 38.5, and 8 = 44.
(The numbers that are 4-8 are the number of lawns, the others and the number of bags of grass seed.)
Which equation represents the relationship between n, the number of lawns, and b, the number of bags of grass seed?
A. b = 5n
B. b = 5.5n
C. b = n + 18
D. b = n + 22
what is it?
So the answer is B?
it is B
Wait is it actually b or-
Yes, the answer is B.
To find the relationship between the number of lawns (n) and the number of bags of grass seed (b), we can look at the given data:
Number of Lawns (n): 4, 5, 6, 7, 8
Number of Bags of Grass Seed (b): 22, 27.5, 33, 38.5, 44
From the data, we can observe that as the number of lawns increases by 1 (from 4 to 5, from 5 to 6, etc.), the number of bags of grass seed increases by a constant amount.
For example:
- When the number of lawns increases from 4 to 5, the number of bags of grass seed increases from 22 to 27.5, which is an increase of 5.5.
- Similarly, for each increase from 5 to 6, 6 to 7, and 7 to 8, the number of bags of grass seed increases by the same constant amount of 5.5.
Therefore, the relationship between n and b can be written as:
b = 5.5n
So, the correct answer is B. b = 5.5n.
