Answer:
(0.1,1.1)
Step-by-step explanation:
we have


Solve the system of equations by graphing
The solution is the intersection point both graphs
The solution is the point (0.081,1.093)
see the attached figure
Round to the nearest tenth ----> (0.1,1.1)
345500=pmt[(1-(1+0.04875/12)^(-12×15))/(0.04875/12)]
Solve for pmt
Pmt=2709.75
