$425

Step-by-step explanation:

if US bank is a

7/4 bank is b

and catch bank is c

the amount in catch bank is equal to the amount in 7/4 bank x 4 so

c = 4b

the amount in us bank is 25% of the 7/4 bank plus catch bank

a = .25(b + c)

the amount in us bank, plus 7/4 bank, plus catch bank equals 2125

a + b + c = 2125
