To find out how much you would save per pound by buying chicken breast at SuperGrocery B instead of SuperGrocery A, we need to calculate the price per pound for both stores.
Step 1: Calculate the price per pound at SuperGrocery A using the equation.
The equation for SuperGrocery A is: \[ y = 6.21x \] To find the price per pound at SuperGrocery A, we can simply use the equation where \(x = 1\):
\[ y = 6.21 \times 1 = 6.21 \]
So, the price per pound at SuperGrocery A is $6.21.
Step 2: Calculate the price per pound at SuperGrocery B.
We know that 2 pounds of chicken breast at SuperGrocery B costs $11.84. To find the price per pound, we divide the total price by the weight:
\[ \text{Price per pound} = \frac{11.84}{2} = 5.92 \]
So, the price per pound at SuperGrocery B is $5.92.
Step 3: Calculate the savings per pound.
To find out how much you would save per pound by buying at SuperGrocery B, subtract the price per pound at SuperGrocery B from the price per pound at SuperGrocery A:
\[ \text{Savings per pound} = \text{Price at A} - \text{Price at B} = 6.21 - 5.92 \]
\[ \text{Savings per pound} = 0.29 \]
Thus, you would save $0.29 per pound by buying your chicken breast at SuperGrocery B compared to SuperGrocery A.
