Question

How do u solve this?

Last Year Wanda divided $12,400 between a savings account and mutual fund. The savings account paid 4% in interest and the mutual fund paid 8% in interest. If she earned a total of $896 in interest, how was her money split between the two accounts?

Answer 1

896 is the total amount. She earned twice as much with the mutual fund as she did with with the savings account. So

896/3=298.67 this she earned with the savings.

She earned twice as much with the mutual. 597.33

Answer 2

10k at 8% 2,400 at 4% you can do this in your head.
