Introduce variables for the amount he invests in each option and write the given information as mathematical equations. Then solve for those variables. Don't forget that he invests all his money in either of those options.

x is money invested in savings
y money invested in bonds
x+y = 100,000
.05x + .11y = 9800
solve for x and y using substitution or elimination
