Your question answers itself. Marty Lister invested \$9000.

Perhaps you want to know how much Marty invested in each asset type. We can let b represent the amount in bonds. Then the total interest is given by
5%(9000-b) + 8%(b) = 525
3%(b) + 450 = 525    (use the distributive property, collect terms)
b = 75/.03    (subtract 450, divide by 3%)
b = 2500
##### Marty invested \$2500 in bonds and \$6500 in stocks.
