Question

Select the correct answer from each drop-down menu. Ashley has 500 songs in his music player. Every week he adds 10 songs to his collection. How many songs will he have in his music player after 20 weeks? At the end of n weeks, the number of songs is given by the function . The output of the function is when the input is 20.

Answer 1

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

Answer 2

500 + 10n

after n weeks there are 500 + 10n songs

500 +10*20 = 500+200 = 700

after 20  weeks there are 700 songs
