    500 + 10n

    after n weeks there are 500 + 10n songs

    500 +10*20 = 500+200 = 700

    after 20  weeks there are 700 songs

    500 (the current collection) + 10 (the weekly addition) x 20 (weeks to add)

    500 + 10*20 (Multiplication comes before addition)

    500+200

    700

    another way I can phrase it

    500 total right now

    each week he adds 10

    after 20 weeks he will have x books

    20 weeks=10 times 20 books added=200 books added

    500+200=700

    answer is 700
