Question

word problem: Jenna's ipod has 250 songs on it and she adds 3 new songs every week. Amy's ipod has 320 songs on it and she adds 1 new song every week. In how many weeks will Jenna and Amy have the same amount of songs on their iPods

Answer 1

So from our word problem we are able to derive two functions Jenna (J) and Amy (A) \[J=250+3x\]and\[A=320+x\]
Do you understand how I derived these?

Answer 2

yes i understand how you got those two equations

Answer 3

So what we want to do now is set them equal and solve for x where x=the number of weeks. We do this because it will tell us where these two functions intersect aka when they both have the same number of songs

Answer 4

so we have
\[250+3x=320+x\]

Do you know how to solve this equation for x?

Answer 5

yes, I got 35 weeks. @FibonacciChick666

Answer 6

that is the correct answer

Answer 7

thank youu(:
