Mr. nielsen invested $250,000 in two different automobile companies. the first earned a 5% profit, and the second earned a 10% profit. if mr. nielson made 3 times as much profit from the 10% investment as he did from the 5% investment, how much did he invest in the company that made 5%?

$100,000

Step-by-step explanation:

Let P be the amount he invested in 5% profit .

then 250,000-P be the amount he invested in 10% profit .

The total profit he earns at 5% =5% of P

⇒The total profit he earns at 5 %=0.05P

Now, The total profit he earns at 10% =10% of (250,000-P)

⇒The total profit he earns at 10%=

According to the question,

Thus, the money he invest in the company that made 5%= $100,000
