Question

You have maxed out your $800 credit card from Utopian One Bank. The interest on the card is 21%. Find the interest and the final cost you pay on this bill. (Hint this problem is computed like sales tax)

Answer 1

Given the question

$800 dollars

21% interest

Caclulate the question how you would calculate the sales tax.

B1 = 800 dollars

B2 = the final cost

$\frac{21\times800}{100}=168$

Interest rate = 168

800 + 168 = 968

968 is the final cost.

Interest rate = $168

Final cost = $968
