Step-by-step explanation:
You can find the answer using the following formula:
i = Prn
i= interest= $400
P= principal
r= rate of interest=0.04
t= time periods= 8
You can replace the values you have in the formula and then, isolate P:
400= P*0.04*8
400=P*0.32
P= 400/0.32
P= 1250
According to this, the answer is that Anna borrowed $1,250.
