Step-by-step explanation:
A rectangular prism's surface area is 
.
2·(10·5+2·5+2·10)=160.
The amount invested at 5% is $12,000 whereas the remaining $15,000 was invested at 4%
What is the amount of annual return for each investment?
The amount of annual return for each investment is determined as the amount invested multiplied by the rate of return
Let us assume that y was invested at 5% and the 27000-y, the remainder was invested at 4%
Total annual return=(y*5%)+(27000-y)*4%
Total annual return=0.05y+1080-0.04y
total annual return=0.01y+1080
total annual return=1220
1220=0.01y+1080
1200-1080=0.01y
120=0.01y
y=120/0.01
y=$12,000(invested at 5%)
amount invested at 4%=27000-12000
amount invested at 4%=$15,000
