x*(1.035) + (4,200-x)*(1.045) = 4,374.00
1.035x + 4,389.00 -1.045x = 4,374.00
15.00 = .01x
x = 1,500 so x (1,500) invested at 3.5% and
(4,200 - 1,500) (or 2,700) invested at 4.5%
Change in value= new price-original price
Change in value=850-10000
Change in value= -9150
%decreased=change in value/original price x 100
%decreased= 9150/10000x100
The answer is 91.5%
