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
