2^-2 x (13x3)-5^3
1/ (2^2) * 39 - 125
1/4 *39 -125
39/4 -125
9 3/4 - 125
factor out -1
- (125-9 3/4)
borrow to subtract the fraction
- (124 4/4 - 9 3/4)
- (115 1/4)
-115 1/4
Let f be the fraction invested at 10%. So (1-f) is the fraction at 7%. After one year the interest is
664 = 8200 f (.10) + 8200 (1-f) (.07) = 8200(.03)f + 8200(.07)
f = (664 - 8200(.07))/(8200(.03)) = .3659 = 36.59 %
Answer: 36.59%
Check:
8200(.3659)*.1 + 8200(1-.3659)*.07 = 664.01 good
