Marilyn has two credit cards, d and e. card d has a balance of $691.64, and card e has a balance of $1,014.22. the minimum monthly payment on card d is 3.57% of the total balance, and the minimum monthly payment on card e is 2.51% of the total balance. how much greater is the minimum payment on card e than on card d? a. $18.85 b. $8.10 c. $11.24 d. $0.77

D. $ 0.77

Step-by-step explanation:

Given,

In card D,

Balance = $ 691.64,

Percentage of minimum monthly payment = 3.57%,

Thus, the minimum payment = 3.57% of 691.64

≈ $ 24.69,

In card E,

Balance = $ 1,014.22,

Percentage of minimum monthly payment = 2.51%,

Thus, the minimum payment = 2.51% of 1014.22

≈ $ 25.46,

∵ Minimum payment in card E > Minimum balance in card D,

Thus, the difference between minimum balance in card E and minimum balance in D = 25.46 - 24.69 = $ 0.77

Hence, OPTION D is correct.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
