Ok, so you have Rock 3150, Country 1800, Rap 2250, Classical 1350 and other 450. How many disks does that total?

OpenStudy (anonymous):

you have to add!

OpenStudy (anonymous):

@DeeBush96 are you there?

OpenStudy (anonymous):

9000

OpenStudy (anonymous):

3150 + 1800 + 2250 + 1350 + 450 = 9000

OpenStudy (anonymous):

good job :)

OpenStudy (anonymous):

3150 + 1800 + 2250 + 1350 + 450 = 9000

OpenStudy (anonymous):

-_- ^

Alright now to find the percentage you divide the amount per category by the total amount (so divide by 9000) and then multiply by 100

OpenStudy (anonymous):

u welcome

OpenStudy (anonymous):

\[\frac{ 3150 }{ 9000 }*100 \] of course since 9000/100 = 90 you can also just divide by 90 instead

OpenStudy (anonymous):

35 %

OpenStudy (anonymous):

correct, now do the same for the others

Just let me know when you need help with the other parts.
