Final answer:
Roberto's minimum payment of $300 will have $156.225 go toward the principal after subtracting the interest for May, which is $143.775.
Step-by-step explanation:
The question is asking us to determine how much of Roberto's minimum payment will go toward the principal of his credit card debt. First, we need to calculate the interest for the month of May using the Annual Percentage Rate (APR). Since the APR is 23%, the monthly interest rate is 23% divided by 12 months, which equals to approximately 1.917%. Applying this to the beginning balance of $7,500, we get $7,500 x 0.01917 = $143.775. This is the amount of interest accumulated for the month of May. Roberto's minimum payment is $300. To find out how much of this payment goes toward the principal, we subtract the interest for May from the minimum payment: $300 - $143.775 = $156.225. Therefore, $156.225 of Roberto's payment will go toward reducing the principal debt.
