Answer
Explanation:
Step1: Convert daily rate to decimal
The daily periodic rate of 0.07% is $0.07\div100 = 0.0007$ in decimal form.
Step2: Calculate monthly finance - charge
The formula for the finance - charge is $Finance\ Charge=Average\ Daily\ Balance\times Daily\ Periodic\ Rate\times Number\ of\ Days$. Substitute the given values: $30\times0.0007\times30$. First, $30\times0.0007 = 0.021$, then $0.021\times30=0.63$. Since the result is in dollars and we want the answer in cents, $0.63\times100 = 63$ cents.
