Question

Answer e please please​

Answer 1

Answer:

x  is invested at 8%, so interest per year is 0.08x.

20000-x is the rest invested at 12%, so interest per year is (20000-x)(0.12)=2400-0.12x

This has to equal the amount of interest gained for 20000*0.11=2200

Therefore, 0.08x+2400-0.12x=2200

-0.04x=-200

multiply both sides by -25

x=$5000 @8% or $400

20000-x=$15000@12%=$1800

They add to $2200, which is 11% of $20000. hope it will help you
