Can someone figure this out???

Question

A man invested a total of $3,000 in two investments. He made a profit of 3% on the first investment and 4% on the ssecond investment. If his total profit was $107, what was the amount of each investment?

Answer 1

a portion of $3K

Answer 2

The 2 amounts invested are x and y.

x+y=3000

also,

.03x+.04y = 107

solving for x,

x=3566.66-4/3 Y

Substituting into the first equation,

3566.66-4/3y + y = 3000

3566.66-1/3Y=3000

1/3Y=566.66

Y=1700

X+1700=3000

X=1300

I could be wrong, but I don't think so.

Can you email me my grade for the test?

Answer 3

.03x + .04(3,000 - x) = 107

Answer 4

Mainecpa's solution is correct he invested $1300 in the first investment and $1700 in the other.
