I'm not sure exactly which type you are meaning since there are four types of expansions, but depending on which specific type here are your answers! :)
On Saturday, Carrie went to the store and bought 4 loaves of bread and 1 gallon of milk for a total of $12.50. The next weekend,
she went to the same store and spent 11.50 on 2 loaves of bread and 2 gallons of milk. The prices had not changed. What is the price for 1 gallon of milk
1 answer:
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
