Answer 1

The cost of one burger is $2.95

The cost of one fry is $1.45

Explanation:

Let

x----> the cost of one burger

y---> the cost of one fry

we know that

`5x+2y=17.65` ----> equation A

`2x+3y=10.25` ----> equation B

Using a graphing tool

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (2.95,1.45)

see the attached figure

therefore

The cost of one burger is $2.95

The cost of one fry is $1.45
