vovikov84 [41]

Answer:

The bank in which Jane has invested.

Step-by-step explanation:

For Tommy's Bank:

P = $400

t = 5 years

I = $76

Simple interest formula is given by

$I=Prt\\\\76=400(r)5\\\\r=0.038\\\\r=3.8\%$

For Jane's Bank:

P = $1000

t = 2 years

I = $82

Simple interest formula is given by

$I=Prt\\\\82=1000(r)2\\\\r=0.041\\\\r=4.1\%$

Since, Jane's bank has higher interest rate. It means one can get higher interest if invest in this bank.

Therefore, we should prefer the bank in which Jane has invested.
