Answer:
Most of the money which can be invested at 6% is $6000
Step-by-step explanation:
Total amount of money = $8500
Let most of the money which is invested at 6% = x
So, most of the money which is invested at 7% = 8500 - x
Now, amount of interest which is guaranteed per year = $535
So, according to the given condition, We have :
6% of x + 7% of (8500 - x) = 535
⇒ 0.06·x + 0.07·(8500 - x) = 535
⇒ 0.06·x + 0.07 × 8500 - 0.07·x = 535
⇒ -0.01·x = -60
⇒ x = 6000
Hence, Most of the money which can be invested at 6% is $6000
