Final answer:
To calculate the monthly interest charge for Fabrice's credit card with a balance of $1,200 and a 20% APR, divide the APR by 12 to get the monthly rate, then multiply by the balance, resulting in an interest charge of approximately $20.04 for the month.
Step-by-step explanation:
If Fabrice has a balance of $1,200 on his credit card and an Annual Percentage Rate (APR) of 20%, the interest charge for this month can be calculated using the formula for simple interest (since we are only looking at a one-month period). Typically, to calculate monthly interest, you would divide the annual rate by 12 (to account for the 12 months in a year) and then multiply that by the balance. Therefore, the monthly interest rate is 20% divided by 12, which is approximately 1.67%.
To find the interest for the month, you would multiply the balance by the monthly interest rate:
$1,200 × 0.0167 = $20.04. Thus, Fabrice's interest charge for this month will be approximately $20.04.
