Given:
Latasha spends $3.35
Helen spends 4 times as much as Latasha.
Dee spends $7.50 more then Helen.
To find:
The amount Dee spends.
Solution:
It is given that, Latasha spends $3.35.
Helen spends 4 times as much as Latasha.
So, Helen spends = 4 × $3.35
= $13.40
Dee spends $7.50 more then Helen.
Dee spends = $13.40+$7.50
= $20.90
Therefore, dee spends $20.90.
Answer: The credit card will paid off within 10 years, therefore the correct option is D.
Explanation:
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,

The total amount have to pay is,

The minimum payment is $20 each month.


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

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.
Essentially, the rule goes as so: odd + odd = even, even + even = even.
Although that may not be the answer you're looking for, it is a math rule that is never debunked and essentially the premises for why you get an even sum practically always depending on the numbers.
Hope this helps!
