Answer:
The price of one gallon of milk is $3.5
Step-by-step explanation:
Let
x----> the price of one loaves of bread
y----> the price of one gallon of milk
we know that
4x+y=12.50 ----> equation A
2x+2y=11.50 ----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2.25,3.5)
see the attached figure
therefore
The price of one loaves of bread is $2.25
The price of one gallon of milk is $3.5
Given:
Consider the equation is:
Some steps of the solution are given.
To find:
The next step of the solution.
Solution:
Step 1: The given equation is:
Step 2: Simplifying right hand side.
Step 3: Simplifying left hand side.
These steps are already given. So, the next step is:
Step 4: Subtracting 3 from both sides.
Therefore, the correct option is (b).
