Answer: $3.42
Step-by-step explanation:
Interest= Principal x Rate x Time
From the question, Principal =$2,150
Rate= 22.9% annually means per year, to calculate the monthly rate, we divide by 12
=22.9%/12 = 1.908% per month
Time = one month, meaning one month out of 12months = 1/12
I is therefore: 2150 x 1.908% x 1/12
= 2150 × 0.01908 x 0.0833
=$3.42
