You have a credit card with a balance of 3500 and interest rate of 15.75%. if you make no payment what is the balance at the end of the next month

Hello Grossjoann, if you have 3,500$ with a interest rate of 15.75% at the end of the month you will get 44.10$ below will explain,

I = $ 44.10

Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 15.75%/100 = 0.1575 per year,
putting time into years for simplicity,
1 months ÷ 12 months/year = 0.08 years,
then, solving our equation

I = 3500 × 0.1575 × 0.08 = 44.1
I = $ 44.10

The simple interest accumulated
on a principal of $ 3,500.00
at a rate of 15.75% per year
for 0.08 years (1 months) is $ 44.10.

Step-by-step explanation:

This is a case of combination since the order does not matter, it only matters that there must be a marble in each one inside, therefore we must apply its formula.

xCn = n! / x! * (n - x)!

n, in this case it would be 4 because we must subtract 2 from the total 6, since there must already be one inside in each display case.

x = 2, since it is the number of showcases.

Replacing:

 2C4 = 4! / 2! * (4 - 2)! = 6

Which means that you can in six different ways.
