Step-by-step explanation:
Maybe the page numbers can be 143 and 246

500 songs in his music player: + 500
every week he adds 10 songs: 10n (n is how many weeks)
equation: s = 10n + 500 (s is the total amount of songs)
after 20 weeks? : plug it in
s = (10 x 20) + 500
s = 200 + 500
s = 700
he will have 700 songs in his music player after 20 weeks
