4 x 1,151.65 = 4,606.60 
This is invested in two accounts. Twenty-five percent is invested in savings (4,606.60 x 25% = 1,151.65). The remainder is invested in a CD (4,606.60 - 1,151.65 = 3,454.95) 

Interest accrued for savings. *Note: The interest rates given are for a full year, but you want to calculate interest for only 60 days. 
1,151.65 x 0.033 x 60/360 = $6.33 
Interest accrued for CD 
3,454,95 x 0.043 x 60/360 = $24.76 
Total interest accrued 
6.33 + 24.76 = $31.09 

Note: 0.033 and 0.043 = 3.3% and 4.3%. Also, the 360 day year is normally used when doing these types of problems.
