2.25P + 1.75P → 4P = 560
P = 140 Kg.
O = 1.75P = 245.
2. Q = P( 1+r)
Q1 = 200( 1+0.06) = $212
Q2 = 212( 1+0.06 ) = $224.72
Q3 = 350( 1 + 0.0575 ) = $370.13
Q4 = 370.13( 1 + 0.0575 ) = $391.41
391.41 + 224.72 = 616.13
Sorry if I was cryptic. I'm feeling lazy tonight. If you need better explanation, I'll oblige.
]]>(2) A = P(1+r)^n
(a) A = 200(106/100)^2 = $224.72
(b) 350(105.75/100)^2 = $ 391.41
Therefore, after two years, he gets $616.13.
2. Eladio invested 200$ at 6% annual interest and 350$ at 5.75 annual interest, both compounded annually. If he makes no deposists or withdrawals, how much will he have after two years?
I totally dont get those!
