## Faman39 3 years ago After how many months will Rita pay \$200 in simple annual interest on a credit card that charges 12% on her \$400 balance?

1. dumbcow

12% is per year right?

2. dumbcow

wait what is the monthly payment

3. brinethery
4. Faman39

it not given there

5. mr.luna

i think you gotta use a exponential function dude, look in your notes and post it here.

6. brinethery

I = Prt I= interest in dollars P = the amount of money r = the rate t = time 200 = (400)*(0.12)(t) t = 200/(400*0.12) This is just a guess, it's been a long time since I've had to do these problems :-/

7. brinethery

And I think time is in years.

8. No-data

Hi Faman! Long time!

9. Faman39

hey data!

10. mr.luna

cuz its gona be 400 times .12 for the first year so the total will be 448 aftier the first year

11. dumbcow

ok i'll assume you are only paying the interest each month 400*r*t = 200 monthly rate is 1% 4 t = 200 t = 50 months

12. No-data

It seems you're getting a lot of help with this. Its nice to see you again!

13. Faman39

so how r u doin? its been a long time, right!

14. No-data

I'm just fine. Loosing some sleep for the sake of math =)

15. Faman39

i missed u guys lot, thing is, i was little busy nowaday, tats y i cant come here like b4. :(

16. brinethery

NM! I didn't REEEAD the problem :-P

17. Faman39

ok no prob lol!

18. brinethery

Okay when you solve for t, it's going to be in years. Convert your years into months.

19. Faman39

u still need to take care of urself, data.

20. Faman39

do u know tat?

21. brinethery

Lol he left

22. Faman39

25. Faman39

27. Faman39

lol!

28. No-data

but you said I need to take care of myself? I did not understand that

29. brinethery

I think she means don't kill yourself over math... oh boy you're gonna have fun in multivariable calculus!

30. Faman39

no ur sayin tat ur losin ur sleep for math, tats y .

31. No-data

ahh ok!

32. Faman39

ya brit is rite!

33. No-data

pls explain to mee brine!

34. Faman39

thank u so much for medals guys.

35. Faman39

oh ur asking from brit or me?

36. brinethery

I gave him a triple integral problem.

37. Faman39

Lol

38. brinethery

The purpose of them is for finding the volume of a weird shape. http://tutorial.math.lamar.edu/Classes/CalcIII/TripleIntegrals.aspx

39. No-data

Well the region of integration is a volume.

40. brinethery

Yeah mr. technical

41. Faman39

lol

42. No-data

hehe sorry =P

43. brinethery

mr. snooty math engineer person

44. brinethery

lolz

45. No-data

what is the meaning of snooty?

46. brinethery

uh... pretentious is a close word? j/k though

47. No-data

49. brinethery

@faman39 you'd better make us proud and take calculus!

50. No-data

51. Faman39

lol me.

52. Faman39

no i m gonna be worst

54. brinethery

*you're

55. brinethery

@faman39 there are so many resources out there. Like Paul's online notes and TheIntegralCalc's channel. That girl is the best at explaining things.

56. Faman39

But ur really brilliant tats y, without knowin anything, lol.

57. Faman39

u passed ur exams.

58. Chlorophyll

59. Faman39

60. Faman39

whats up?

61. Chlorophyll
