Answer:
There are 26 investors which contributed 6,000
And 34 investors which contributed 3,000
Step-by-step explanation:
You need to set up a two equation problem
[tex]\left \{ {{258,000=6,000y+3,000x} \atop {60=y+x}} \right.[/tex]
Now you have to clear "x" or "y" from the second equation:
[tex]y = 60 - x[/tex]
And replace on the first equation:
[tex]258,000 = 6,000 (60 - x) + 3,000x\\258,000 = 360,000 - 6,000x + 3,000x\\3,000x = 360,000 - 258,000\\x = 102,000/3,000\\x = 34[/tex]
And now you use this "x" vale on the second equation
[tex]60 = y + x\\60 = y + 34\\60 - 34 = y\\y = 26[/tex]
There are 26 investors which contributed 6,000
And 34 investors which contributed 3,000
