Answer:
She could purchase from stores A, D and E.
Step-by-step explanation:
She needs 8 cups so I multiplied each price by 8;
Store A 0.49(8)=$3.92
Store B 0.51(8)=$4.08
Store C 0.55(8)=$4.40
Store D 0.48(8)=$3.84
Store E 0.45(8)=$3.60
Multiply you first equation by 2 to get 4x + 10y = 22
Now the x terms can be eliminated and cancelled out using elimination.
4x + 10y = 22
4x + 3y = 1
To eliminate you need to "subtract", so you need to multiply one of the equations by -1.
4x + 10y = 22
-4x -3y = -1
------------------
0 + 7y = 21
y = 3
Now plug 3 into either one of the equations to get x.
33% of decrease.
150-100=50
50 is 1/3 of 150
1/3= 33%
