Suppose $50,000 is divided into two bank accounts. one account pays 4% simple interest per year and the other pays 6.4%. after five years there is a total of $12,000 in interest between the two accounts. how much was invested into the bank account that pays 6.4% simple interest (rounded to the nearest cent)?

$33333.33

Step-by-step explanation:

Suppose x invested into the bank account that pays 4% simple Interest

5x4%x+5x6.4%(50000)= 12000 { The interest due is equal to interest}

4x+6.4x50000-6.4x=240000

2.4x=80000

x=33333.33

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
