Answer:

\$421.60

Step-by-step explanation:

we know that

The simple interest formula is equal to

A=P(1+rt)

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=1\ year\\ P=\$400\\ A=?\\r=5.4\%=5.4/100=0.054

substitute in the formula above

A=400(1+0.054*1)

A=400(1.054)

A=\$421.60

Remember that Interest is equal to

I=A-P

I=\$421.60-\$400=\$21.60
