Aaron invested a total of $4,100, some in an account earning 8% simple interest, and the rest in an account earning 5% simple interest. how much did he invest in each account if after one year he earned $211 in interest? select one: a. $200 at 8%, $3,900 at 5% b. $3,200 at 8%, $900 at 5% c. $900 at 8%, $3,200 at 5% d. $3,900 at 8%, $200 at 5%

He invest $200 at 8%, $3,900 at 5% .

Step-by-step explanation:

Let P be the amount Aaron invested in account with 8% simple interest then 4100-P denote the amount Aaron invested in account with 5% simple interest .

We know that the simple interest with rate r% for t years is given by:-

It si given that after 1 year total interest = !211

Then,

4100-P=4100-200=3800

Hence, He invest $200 at 8%, $3,900 at 5% .
