.015x+.03(2x)= 1350
.075x = 1350
x= 1350/.075= 1,350,000/75= 450,000/25
= $18,000 at 1.5%
2x= $36,000 at 3%
3% of 36000= 1080
1.5% of 18000= 270
1080+270=1350

Let X represent the initial amount invested at 1.5%. We also know 2X was invested at 3%. So the equation becomes: x*0.015+2x*0.03=$1,350 x*(0.015+0.06)=$1350 x*0.075=$1350. Solving for X x=$18,000 @ 1.5% & $36,000 @ 3%09/15/24
