Step-by-step explanation:
So in this systems of equations, we know the prices of the items, so the coefficients will represent how many Mary is getting of that item. So you can represent amount of bread as the variable b and the amount of milk as the variable m. On the right will be the total amount spent, since multiplying the price by how much you buy should get you the price
So since at store A, she spends 44.20 and bread costs 2.20 and milk costs 3.60 you get
Since at store B, she spends 44.70 and bread costs 2.50 and milk costs 3.40 you get the equation:
Answer:
B
X= 7.5
Y= -5
Step-by-step explanation:
In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.
