<h3 /><h3>What is a credit card?</h3>

A credit card refers to a payment mechanism that helps both consumer and commercial business proceedings, including purchases and cash advances.

Computation of credit card's balance:

<u>Amount of </u><u>Card H </u><u>after 3 years:</u>

Given,

Principal(P) = $1,186.44

Interest Rate(r) = 14.74%

Number of time period(n) = 3 years.

Applying the above values in the formula given in the question:

$\text{A} = \text{P}(1+ \dfrac{r}{n} )^n^t\\\\\\\text{A} =\$1,186.44(1+ \dfrac{14.74\%}{3} )^3\\\\\\\text{A}= \$1792.2$

<u>Amount of</u><u> Card I </u><u>after 3 years:</u>

Principal(P) = $1,522

Interest Rate(r) = 12.05%

A number of the time periods (n):

$12\text{Months}\times3\text{Years} = 36 \text{Months}$

Again, apply the above values in the formula given in the question:

$\text{A} = \text{P}(1+ \dfrac{r}{n} )^n^t\\\\\\\text{A} =\$1,522.16(1+ \dfrac{12.05\%}{12} )^3^6\\\\\\\text{A}= \$3,371.58$

Now we take the difference between both the credit cards, we have:

$\text{Amount of Credit Card I}-\text{Amount of Credit Card H}\\\\=\43,371.58-\$1,792.2\\\\=\$1,579.38$

Therefore, card H's balance is decreased by $1579.3 than a card I.
