Answer:
Unit rate:
2 dollars per pound : Equation 2 and Table 2
dollars per pound : Table 1
4 dollars per pound : Equation 1
Explanation:
Unit rate means the money required to buy 1 pound of the given quantity.
Table 1:
d p
2 4
6 12
10 20
Here, from the first row, we observe that,
Using unitary method;
Cost of 4 pounds = $2
∴ Cost of 1 pound =
dollars
Therefore, the unit rate is
dollars per pound.
Equation 1:

Now, unit rate can be calculated by plugging in 1 for 'p'. This gives,

So, unit rate is 4 dollars per pound.
Equation 2:

Now, unit rate can be calculated by plugging in 1 for 'p'. This gives,

So, unit rate is 2 dollars per pound.
Table 2:
d p
2 1
6 3
10 5
Here, from the first row, we observe that,
Cost of 1 pounds = $2
Therefore, the unit rate is 2 dollars per pound.
