anonymous one year ago I WILL MEDAL/FAN Please help me! (NO ANSWERS PLEASE) :) Bella plans to put \$200 into a savings account. She can place her money into an account represented by p(x) = 3x + 200, or into another account represented by n(x) = 200(1.04)x. Which account has the highest value in 4 years? Which account has the highest in 15 years?

p(x) has the highest value in 4 years; p(x) has the highest value in 15 years n(x) has the highest value in 4 years; p(x) has the highest value in 15 years n(x) has the highest value in 4 years; n(x) has the highest value in 15 years p(x) has the highest value in 4 years; n(x) has the highest value in 15 years

An easier way to get someone to look at it for you is that when you post the question, type in big letters: "MEDAL WILL BE AWARDED" or "WILL MEDAL" or something like that. I know it works with me almost always. Why don't you try reposting the question?

Trust me, It Really Helps

$p(x) = 3x + 200\\p(4)=3\times 4+200$ $n(x) = 200(1.04)^x\\ n(4)=200\times (1.04)^4$ compare and contrast as the teachers say

wait what? @satellite73

plug in the numbers, see what you get

He didn't understand what you told him last time

19. anonymous

I did not :( xD I am so slow to catch on, you guys might as well try to explain this to a blind turtle.

20. anonymous

ok lets go slow

21. anonymous

I totally understand the feeling

22. anonymous

you have two functions, right? one is $p(x) = 3x + 200,$

23. anonymous

the other is $n(x) = 200(1.04)^x$

24. anonymous

you are asked "Which account has the highest value in 4 years? "

25. anonymous

to find the answer, where you see an $$x$$ replace it by a $$4$$ the first one to compute is $p(4)=3\times 4+200$ what is that number?

26. anonymous

did i lose you there?

27. anonymous

I'm not sure. He pops in and out all the time

28. anonymous

oh

Lets try calling him

sorry if that was counted as mass- tagging :(

Look at what satellite73 said. Just plug the numbers into both functions and whatever gives you the largest number is the bank account to go with

40. anonymous

I did that and concluded that C would be the answer? @Australopithecus

41. Australopithecus

that is correct.
