Mr. rodriguez invests half of his money in land a tenth in stocks herrin 20th in bonds he puts the remaining 35000 in his savings account what is the total amount of money that mr. rodriguez saves and invests

Let us assign the variable x to the total amount of money Mr. Rodriguez owns. The total amount of money would then be equal to the portion of money he spent on land, in stocks, in bonds and in his saving accounts. You have to learn first that the first three expenses are forms of investments. Investments on land are called real estates which are based on properties. The other type of investments are stocks and bonds which are based on paper assets. The only difference is that stocks mostly comes from private companies, and bonds come from the government agencies. Nevertheless, these are all investments. 

Now, we create an equation to determine x. By the way, I am confused with the statement that says " Herrin 20th'. I don't really know what that means, so I'll just assume the the bonds were allocated with one-twentieth of his total money. So, the equation that we can formulate is:

x = 1/2 x + 1/10 x + 1/20 x + 35,000

There is one unknown in the equation. So, we can explicitly solve for x:
x = 100,000

Therefore, the total amount of money Mr. Rodriguez has is 100,000. The allocation for investments is equal to:

(1/2 + 1/10 + 1/20)(100000) = 65,000

Lastly, the remaining money of 35,000 is placed on his savings account.
