You invested ​$16,000 in two accounts paying 2 % and 4 % annual​ interest, respectively. If the total interest earned for the year was $ 600, how much was invested at each​ rate?

Question

answers in percent please

Answer 1

T=amt at 2% and F=amt at 4%

T+F=16000

.02T+.04F=600

Divide the 2nd equation by 0.2: T+2F=30000

Subtract this equation from the 1st equation

F=14000

T=2000
