Elena-2011 [213]

Answer: $100,000

<u>Step-by-step explanation:</u>

Land + Stocks + Bonds + Savings = 100%

$\dfrac{1}{2}x$ + 0.1x + $\dfrac{1}{20}x$ + 35,000 = 1.00x

= 0.5x + 0.1x + 0.05x + 35,000 = 1.00x

= 0.65x + 35,000 = 1.00x

35,000 = 0.35x

$\dfrac{35,000}{0.35}=\dfrac{0.35x}{0.35}$

100,000 = x
