She spent $7.44 because 3.28 + 1.27 + 0.56 + 2.33 = 7.44
        
             
        
        
        
Assuming the price of the pool does not change, then
Additional interest required is 4500-3750=750
using
I=Pit, we set up equation
750=3750*0.055*t
Solve for t
t=750/(3750*0.055)=3.64  years.
So will need to wait 3.64 years, or rounded up to 4 years.
