crimeas [40]

Answer:

In this question if g and h is constant then;

111 = 14g

14g = 111

g = 111/14

g = 27.7 ~ 28

And also,

13.65 = h + 4.88

h + 4.88 = 13.65

h = 13.65 - 4.88

h = 8.77

Answer: The credit card will paid off within 10 years, therefore the correct option is D.

Let the number of years in which the credit card will aid of be x.

It is given that amount owed on credit card is $1000 with interest rate 27.99%.

So the amount of interest is calculated as,

$1000\times \frac{27.99}{100} =\$27.9$

The total amount have to pay is,

$\$1000+\$279.9=\$1279.9$

The minimum payment is $20 each month.

$x=\frac{1279.9}{20}$

$x=63.995$

So, the credit card will paid of in 63.995 months. We know that 1 year =12 months.

$\frac{63.995}{12} =5.33$

Therefore, the will paid of in 5.33 years, s we can say that the credit card will paid off within 10 years, therefore the correct option is D.
