Danielle put $582 in the bank. Her brother put 3 times as much money in the bank. Her sister put 1/3 as much money in the bank. How much money combined did Danielle’s brother and sister put in the bank?

Answer 1

Danielle's brother put 3 x $582 = $<<3*582=1746>>1746 in the bank.
Her sister put $582/3 = $<<582/3=194>>194 in the bank.
So, Danielle's brother and sister put a total of $1746 + $194 = $<<1746+194=1940>>1940 in the bank. Answer: \boxed{1940}.
