Answer:
The cost of one bottle of water is $1.25
The cost of one apple is $0.75
Step-by-step explanation:
Let
x------> the cost of one bottle of water
y-----> the cost of one apple
we know that
2x+4y=5.50 ----> equation A
3x+5y=7.50 ----> equation B
Solve the system of equations by graphing
The solution of the system of equations is the intersection point both graphs
The intersection point is (1.25,0.75)
see the attached figure
therefore
The cost of one bottle of water is $1.25
The cost of one apple is $0.75
