substitute equation C in equation B

----> equation D

we have

----> equation A

----> equation D

Solve the system of equations A and D by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (98,22)

see the attached figure

Find the value of z

---->

therefore

The amount that Hannah has is $98

The amount that Francine has is $22
