📝 Answered - Harvey has a credit card that uses the previous balance method. The opening balance of one of his 30-day billing cycles was $2790, but that was his balance for only the first 6 days of the billing cycle, because he then paid off his entire balance and didn't make any new purchases.

[tex]\left(\frac{0.21}{365} \cdot 30\right)\left(\frac{6 \cdot \$ 2790+24 \cdot \$ 0}{30}\right)[/tex] B. [tex]\left(\frac{0.21}{365} \cdot 30\right)(\$ 0)[/tex] C. [tex]\left(\frac{0.21}{365} \cdot 30\right)(\$ 2790)[/tex] D. [tex]\left(\frac{0.21}{365} \cdot 30\right)\left(\frac{6 \cdot \$ 0+24 \cdot \$ 2790}{30}\right)[/tex]
