Current worth
depreciates by  in 3 years.
 in 3 years.
time=  19 years 
depreciates rate=?
Using formula:

System of equations subtraction method
In the addition/subtraction method, the two equations in the system are added or subtracted to create a new equation with only one variable. ... Substitute the variable back into one of the equations and solve for the other variable. Check the solution--it should satisfy both equations.
 
        
                    
             
        
        
        
456.98-10-14.95-6.07-109.10-30=<span>286.86
So her new </span>checkbook balance is $286.86
        
             
        
        
        
The correct answer is 1.75 because the equation is p=.50+1.25 which equals 1.75.
