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 second investm
ent. if his total profit was $107, what was the amount of each investment?
1 answer:
Let the first investment be x
and second be 3000-x
so 3%of x + 4% of (3000-x) = 107
By solving x = 1300
First investment is 1300
second investment is 1700
