PLEASE HELP!!!! 100 POINTSS

shen invested his savings in two investment funds. the $3000 that he invested in fund a returned a 2% profit. the amount that he invested in fund b returned a 7% profit. how much did he invest in fund b, if both funds together returned a 4% profit? amount invested in fund b:

Answer 1

0.04 *(3000 + b) = 0.02*3000+0.07*b

120+0.04b=60+0.07b

120-60=0.07b-0.04b

60=0.03b

So b=2000
