Alex787 [66]

Answer:

\frac{2}{25}

Step-by-step explanation:

Given expression,

\frac{\frac{2x-4}{30} }{\frac{15x-30}{18} }

=>\frac{\frac{2(x-2)}{30} }{\frac{15(x-2)}{18} }

We see that (x-2) is common in both numerator and denominator

hence canceling out we get:-

\frac{2*18}{30*15}=\frac{2}{25}

Answer=\frac{2}{25}

How much interest will you have to pay for a credit card balance of $1,034 that is 1 month overdue, if a 17% annual rate is char
frosja888 [35]

Ans. Since the annual rate is not compunded (for example, compounded monthly) you will have to pay in interest $27.41, and the total payment is $1,061.41

Step-by-step explanation:

Hi, since the balance is 1 month overdue, it means that you owe 2 months of interest to this obligation, but before we start finding the interest of your credit card, first let´s find the effective monthly equivalent rate for that 17% annual interest rate.

The formula is as follows.

Therefore

So your monthly interest rate is 1.317%. Now let´s find the amount of interests that you have to pay for 2 months. This is the formula.

Where "n" is the period of time in months that you owe to the financial institution. The result of that is:

This way, interest are = $27.41 and the total amount that you will have to pay is:

<h2>Payment=Present Value+Interest=1,034+27.41=1,061.41 </h2>
