To learn how to set up and solve this sort of exercise, tryhere.

Then:

. . .invested:

. . . . .at 4%: x

. . . . .at 2.25%: 33,000 - x

. . .interest:

. . . . .at 4%: 0.04x

. . . . .at 2.25%: ??(33,000 - x)

Complete the table. Sum the two interest expressions, and set equal to the given total. Thensolve the linear equation. Back-solve for the required values.
