Marilyn has two credit cards, d and

Answer 1

1) let's count the payment that you would do on the card E
2.51% of $1,014.22

percentage can be exchanged to numbers like this:

x%=x*0.01, so 2.51 percent is 0.0251:

So now we multiply:
0.0251*1014.22=25.46

 2) now let's count  Card D payment:
3.57%*691.64=0.0357*691.64=24.69

and the difference is:

25.46-24.69=0.77


So the answer is D)!
